Book summary “I Hate You - Don't Leave Me”: summary

Introduction

You may feel exhausted by sudden explosions of rage, intense demands for closeness, and terrifying threats of abandonment from someone you love. Relationships with individuals suffering from Borderline Personality Disorder often feel like an impossible emotional minefield where you constantly walk on eggshells. You might wonder if this severe instability stems from personal weakness or an untreatable mental illness that will never improve.

Jerold J. Kreisman argues in I Hate You - Don't Leave Me that Borderline Personality Disorder is a distinct and highly treatable condition rather than a permanent life sentence. The book explores the medical, psychological, and social dimensions of the illness while providing practical communication tools for relatives and therapists. You will learn how to navigate crises, set firm boundaries, and understand the complex origins of borderline behavior.

• How do genetic vulnerabilities and childhood trauma interact to cause the condition?
• Which specific communication systems help de-escalate intense emotional outbursts?

1. The World of Borderline Personality Disorder

Borderline Personality Disorder is one of the most common personality disorders, yet it remains underrecognized and heavily stigmatized by the public and clinicians. Jerold J. Kreisman and Hal Straus note that patients with Borderline Personality Disorder (BPD) are frequently dreaded by clinicians as difficult to treat. The disorder coexists with numerous other psychiatric and medical conditions, often consuming a disproportionate amount of mental health services.

Borderline Personality Disorder is a prevalent, highly stigmatized condition defined by emotional hemophilia, severe instability, and the defense mechanism of splitting.

Estimates show that 19 million or more Americans exhibit primary symptoms of BPD. Between 3 to 6 percent of the American population has BPD. The condition accounts for 10 percent of psychiatric outpatients and 20 percent of psychiatric inpatients. Among all patients seeking psychiatric care, 15 to 25 percent are diagnosed with BPD. Furthermore, 90 percent of BPD patients share at least one other major psychiatric diagnosis. The authors categorize this condition as part of the Third World of mental illness.

Clinical Characteristics

Individuals with BPD suffer from an extreme lack of emotional regulation, which the authors term emotional hemophilia. Lacking a clotting mechanism to moderate feelings, borderline individuals bleed emotionally from minor psychological pricks. This vulnerability leads to chronic emptiness, explosive mood changes, and desperate impulsive acts to feel alive.

Jennifer, a 28-year-old personnel manager, presented with severe gastric pain due to stress. She had a history of turbulent relationships, alternating dress styles ranging from mature business suits to childlike knee socks, and episodes of impulsive behavior and self-derogation. Dr. White had been treating Jennifer for minor medical problems prior to hospitalization for 5 years. Patients like Jennifer experience extreme mood swings, internal emptiness, and frantic fears of abandonment. They use defense mechanisms like splitting and adopt various repertory players persona roles to cope with a weak core identity.

Self-destructive tendencies and suicidal gestures are defining criteria and extremely common hazards among individuals with BPD. Many suicide attempts are executed not necessarily with the intent to die, but as an extreme measure to feel sensation or confirm existence amidst crushing emotional numbness. Studies show that 70 percent of BPD patients attempt suicide, and 8 to 10 percent result in documented death by suicide.

Diagnostic Criteria

The diagnosis of Borderline Personality Disorder requires an individual to meet at least five out of nine specific categorical criteria defined in the DSM-5. These 9 categorical criteria interact dynamically like engine pistons. They are grouped into 4 primary areas: mood instability, impulsivity and dangerous uncontrolled behavior, interpersonal psychopathology, and distortions of thought and perception.

Splitting is the primary defense mechanism in BPD, characterized by the rigid, black-and-white separation of positive and negative perceptions of self and others. Because they cannot tolerate human ambiguities or reconcile contradictory traits, borderline individuals categorize people entirely as heroes or villains, swinging rapidly between idealization and devaluation. You may observe them labeling someone as a Good Joe one moment and a Bad Joe the next.

Long-term studies demonstrate that BPD has a favorable prognosis, with a vast majority of patients achieving significant remission and recovery over time. Although acute symptoms like self-mutilation and impulsivity diminish with time and ongoing therapy, many patients continue to face residual challenges in vocational and social environments. Long-term studies tracking patient remission over a 16-year follow-up duration found that 99 percent of borderline patients achieved at least two years of remission. Moreover, 78 percent of borderline patients experienced an eight-year remission, alongside 34 percent recurrence rates observed in longitudinal tracking. After a timeframe of 10 years, full and complete recovery is achieved in 50 percent of patients, with good social and vocational functioning.

2. Clinical Definition and Core Symptoms

Borderline Personality Disorder is an enduring trait disorder resulting from a mix of temperament and character, unlike temporary state disorders. You can distinguish BPD from episode-limited conditions like depression or schizophrenia because borderline traits are inflexible, maladaptive, and enduring. The DSM-5 notes 10 personality disorders, with BPD relying primarily on psychotherapy for improvement.

Diagnosed by meeting five out of nine specific descriptive criteria, BPD manifests as frantic efforts to avoid abandonment, identity disturbance, intense rage, and chronic emptiness.

Fear of Abandonment

Borderline individuals experience temporary aloneness as catastrophic extinction or perpetual isolation, leading to profound depression and rage. Because you lack a solid internal self, you rely on the external physical presence of others to feel real. You adhere to a philosophy of others acting upon you to confirm your existence.

Marilyn Monroe expressed a hatred of being alone, noting that without people constantly around her she would fall into an endless and terrifying void.

Relationships are volatile due to an oscillation between clinging dependency and fearful avoidance, coupled with an empathy paradox. You swing between idealization and devaluation, caught in a tug-of-war between a desire to merge and a fear of engulfment. You exhibit a borderline empathy paradox where you possess heightened social sensitivity to negative cues but are impaired in integrating interpersonal information and lacking object constancy.

Sam, a college student with BPD, characteristically approached inaccessible women, but whenever his overtures were accepted, he immediately devalued them as no longer desirable.

Impulsivity and Mood Shifts

A marked and persistent identity disturbance leaves you with a chronic sense of inauthenticity and feeling like a fake. Lacking a constant core sense of identity, you evaluate your worth relatively against others and moment-by-moment rather than through enduring traits. You feel you are constantly faking it and are terrified of being exposed as frauds, leading you to seek perfectionism or radically change jobs, friends, or lifestyles.

Aaron dropped out of college, joined the Moonies to assuage his aimlessness, left after two years, wandered, briefly returned, and ultimately attempted suicide after leaving again due to a lack of stable goals.

Impulsive and self-destructive behaviors serve as mechanisms to escape emotional numbness, punish the self, or communicate pain. Impulsivity across areas like substance abuse, reckless driving, or binge eating arises from living entirely in the immediate present without past experience or future hope. Self-mutilation and suicide threats function as a cry for help, a way to induce physical pain to pierce an insulating numbness, or an expiation for perceived guilt. Seventy percent of BPD patients attempt suicide, alongside a 10 percent suicide completion rate and a 75 percent history of self-malformation.

Jennifer fulfilled her need to self-inflict pain by scratching her wrists, abdomen, and waist, leaving deep fingernail marks that she could easily cover with clothing.

Affective instability causes severe, rapid mood shifts that last for hours rather than days and react disproportionately to environmental triggers. Unlike bipolar disorder where mood swings last from days to weeks and represent radical departures from a normal baseline, BPD mood variations are transient and typically alternate between hyperactive states and cynicism or depression.

Audrey was giddy with excitement after receiving flowers, but upon taking a phone call from her complaining mother, she instantly mutated into a raging shrew screaming at her partner.

Chronic emptiness and intense, uncontrollable anger are persistent core symptoms that sabotage relationships and therapeutic alliances. Chronic emptiness creates a painful existential boredom and angst that drains motivation and drives impulsive ventures. Accompanying this, inappropriate and intense rage erupts disproportionately to minor triggers, pushing away loved ones and frequently targeting mental health professionals during treatment.

Vincent van Gogh chased his friend Paul Gauguin with a butcher knife after a trivial argument over painting styles, and then turned the rage inward to slice off part of his own ear.

3. Roots and Causes: Nature, Nurture, and Development

Borderline personality disorder arises from a multifactorial combination of genetic vulnerabilities and environmental experiences rather than a single definitive cause. Studies indicate that roughly 42 to 55 percent of borderline personality disorder features are attributable to genetic influences, while the remaining derivation stems from environmental and sociocultural stressors. Multiple chromosomal loci, neurotransmitter dysfunctions, and brain structure abnormalities interact with developmental trauma and chaotic family dynamics.

BPD arises from genetic vulnerabilities interacting with environmental trauma and developmental failures during Mahler's separation-individuation phases.

Biological Factors

First-degree relatives of individuals with borderline personality disorder show significantly higher rates of personality, mood, impulse, and substance abuse disorders due to heritable general factors. Research demonstrates that a family member of someone with the disorder is almost four times more likely to develop it than a nonrelative. Heritable traits heavily influence impulsivity, while biological correlates involve neurotransmitters like serotonin, norepinephrine, dopamine, glutamate, oxytocin, and cortisol stress response irregularities.

Borderline personality disorder is associated with functional and structural brain imbalances, specifically hyperactivity in emotional limbic areas and decreased activity in rational prefrontal regions. Borderline patients display hyperactivity in limbic areas like the amygdala, which manage anger, fear, and emotionality, alongside decreased activity in the prefrontal cortex, which controls rational thought and emotion regulation. This imbalance impairs the brain's ability to reason through and control primitive, impulsive reactions.

Object Relations Theory

Object relations theory explains that infant development progresses through distinct phases from autism to symbiosis and separation-individuation, forming the foundation for later mental health. Margaret Mahler's model divides infant development into the autistic phase, lasting one to two months, the symbiotic phase, lasting four or five months, and the separation-individuation period spanning ages two to three years. Successful navigation through these phases requires balancing autonomy with dependency and overcoming the fears of engulfment and abandonment.

The separation-individuation period breaks down into four distinct developmental subphases:

• differentiation phase, spanning 5 to 8 months;
• practicing phase, spanning 8 to 16 months;
• rapprochement phase, spanning 16 to 25 months;
• object constancy phase, spanning 25 to 36 months.

During differentiation and practicing, infants explore movement away from the caregiver. In the rapprochement phase, children realize their separate identity and require a supportive refueling reservoir from parents. Parental failure through premature pushing or suffocating symbiosis leads to chronic fears of abandonment and engulfment.

Individuals with borderline personality disorder fail to reach object constancy, remaining fixated at an earlier developmental stage where splitting and defense mechanisms dominate. Normal development integrates an all-good and all-bad parent into a single, permanent entity that exists even when absent. Borderline adults cannot achieve this integration, perceiving people as entirely good or bad and relying on transitional objects like security blankets or childhood items to soothe internal distress.

Adolescence repeats the separation-individuation conflicts of infancy, and severe childhood traumas significantly increase the probability of developing borderline personality disorder. Adolescents react to peers or oppose parents rather than acting from internal needs, mirroring infant rapprochement struggles. Early battlefields marked by parental loss, neglect, physical or sexual abuse, and broken homes propel individuals into intense searches for identity, sometimes fueling artistic ambition or emotional instability.

Marilyn Monroe and Princess Diana both experience absent or rejecting parents during early childhood, driving intense searches for identity and public roles while struggling with deep feelings of unworthiness.

4. The Borderline Society and Environmental Stressors

Contemporary Western culture lacks structure, historical constancy, and reliability, creating an environment that elicits or breeds borderline traits on a wide scale.

Social factors act as indirect influences or exacerbative triggers for individuals suffering from borderline syndrome. Modern society is characterized by rapid technological advancement, increased geographical mobility, rising divorce rates, and a loss of traditional roles. This culture deprives you of outside sources of stability and self-worth validation.

Just as an infant ventures away from the mother during the separation-individuation phase and returns for reassuring warmth, you need supportive community anchors. Modern economic pressures, two-income households, and frequent relocations strip away stabilizing roots, leaving children and adults adrift in unchartered waters.

• 60 percent of marriages for couples between the ages of twenty and twenty-five end in divorce.
• 50 percent of marriages end in divorce for those over twenty-five.

Lisa grew up in a chaotic household with a distant, demanding father who frequently relocated the family and criticized her achievements. Her mother was often incapacitated by pain pills and tranquilizers. Lisa's family moved constantly from Omaha to St. Louis, Chicago, and New York for her father's career, making her feel like a kidnap victim or a slave and causing her to vow never to make another friend.

Trauma and Abuse

Child abuse and emotional neglect severely damage self-esteem, destroy trust, and initiate a self-perpetuating cycle of violence and interpersonal dysfunction.

Emotional abuse takes forms such as degradation, unavailability or neglect, and domination through extreme threats. Abused children frequently grow up to become abusers themselves and display severe attachment difficulties, poor impulse control, and an impaired ability to discriminate in relationships.

• About 5.8 million children were involved in an estimated 3.2 million child abuse reports in the United States in 2007.
• About 30 percent of abused and neglected children will later abuse their own children.

Living only for the moment without connection to predecessors or posterity breaks the perceptual link to the future. Threatening events such as nuclear annihilation, terrorism, global warming, and school shootings foster hopelessness, pessimism, and unrealistic fatalism among adolescents. A 2008 study published in the Journal of Adolescent Health based on surveys of 4,201 adolescents between 2002 and 2005 found that about one out of young people, or 6.7 percent, expected to die before age thirty.

5. Communicating and Coping Using the SET-UP System

The SET-UP communication system provides a structured framework of Support, Empathy, Truth, Understanding, and Perseverance to de-escalate crises.

Originally developed for hospital staff and adapted for loved ones, SET-UP combines immediate communication strategies with long-term attitudes. SET stands for Support, Empathy, and Truth, which are used in balanced proportion during confrontations. UP stands for Understanding and Perseverance, representing the overarching commitment needed to maintain the relationship and pursue goals over time.

Failing to communicate any single component of the SET system leads to predictable negative reactions and stalls dialogue with a borderline individual. If the Support stage is missed, the individual accuses others of not caring and tunes out. If Empathy is missing, they feel misunderstood and devalue the speaker's responses. If Truth is omitted, a dangerous situation arises where the individual interprets acquiescence as confirmation that others are responsible for them, which eventually leads to a catastrophic collapse of the relationship when unrealistic expectations are frustrated.

• Support: Invoke a personal 'I' statement expressing concern, worry, or a desire to help.
• Empathy: Acknowledge the sufferer's anguish and chaotic feelings using a 'You' statement without using condescending sympathy.
• Truth: Recognize the reality of the situation, emphasize personal accountability, and address practical objective issues without blaming or punishing.
• Understanding: Acknowledge the anguish of the illness to allow for patience and recognize necessary adjustments without granting absolution from responsibility.
• Perseverance: Consistently hang in there and maintain commitment to treatment and the relationship despite ongoing frustrations and disappointments.

Borderline individuals lack object constancy and must constantly test relationships and situations out of fear that trusted figures will turn into absolute betrayers. Because the universe lacks predictability, the individual believes every day must begin anew to prove the world can be trusted. Attempts at reassurance are never-ending because any display of independence or separate functioning by a partner triggers terror and rage.

Pat engaged in intense marital relationships where she initially idealized her partners as strong protectors, but flew into brutal rages when they exhibited normal independent behavior like going to work. At age twenty-nine, Pat experienced her second divorce amid these cyclical patterns of testing.

Setting Limits

Borderline individuals frequently place others in no-win situations by communicating contradictory messages through words and behavior. A person with BPD splits off negative choices and projects them onto a partner, maintaining a self-righteous martyr role regardless of how the partner responds. Using SET-UP principles helps address the underlying ambivalence, such as acknowledging both a desire to die and a hidden wish to be saved during suicidal threats.

Gloria tells her husband Alex that she plans to kill herself but forbids him from seeking help, creating a trap where any action he takes is criticized.

Enforcing clear limits and backing up intentions with predictable actions is essential, as idle threats worsen borderline testing behavior.

Acquiescing to manipulative testing reinforces the disorder. Establishing written contracts with clearly defined expectations, agreed consequences, and consistent follow-through helps break enabling cycles and encourages the individual toward self-sufficiency.

Mr. and Mrs. Hopkins established a written contract with their twenty-nine-year-old son Kevin, outlining household tasks and job requirements with the consequence of having to leave the house, which ultimately led him to secure a job and move out with a roommate.

• Agree with other family members or support figures on what limits will be set and what demands will be made.
• Expect the individual to challenge these limits and remain prepared to proceed with the proposed consequences.
• Present expectations clearly, such as through a written contract outlining tasks, jobs, or educational programs over a specified time period.
• Provide resources such as names and numbers of shelters or family friends if housing consequences must be enforced.

6. Recognizing BPD and Managing Symptoms

Loved ones can manage borderline symptoms by using transitional objects, setting boundaries, avoiding toxic phrases, and responding calmly to emotional outbursts.

Abby, a twenty-three-year-old fashion model, was treated successfully for alcoholism and then bulimia, but later developed severe panic attacks. A psychiatric consultant recognized these as BPD symptoms rooted in her ambivalent relationship with her parents. Adults with BPD can often function well outwardly, but sudden extreme outbursts or self-harm are common manifestations. Treating only secondary conditions such as depression or chemical dependency leaves the core BPD unresolved and leads to frustration.

Stephanie was subjected to constant emotional abuse and criticism by her father, who called her chubby and stupid. As an adult, she constantly doubted herself and tried to sabotage her relationship with Ted by testing his loyalty. Blaming oneself makes the unpredictable abuse seem controllable and avoids the terrifying realization that dependent caregivers are incompetent.

Coping Strategies

The dread of being alone causes clinging neediness and demands for constant reassurance. Establishing a reliable level of connection helps soothe these anxieties without enabling endless demands.

• Employ transitional objects such as a photo, an article of clothing, or a favored sweater.
• Prepare for future separations in advance by discussing them and supplementing with positive plans.
• Encourage alternative comfort sources like friends, club meetings, or workout sessions.
• Establish balanced, disciplined boundaries by defining a reliable level of connection you can consistently fulfill.
• Seek professional help immediately for suicidal threats or actions.
• Safeguard the environment by removing medications, sharp instruments, and weapons.
• Explore alternative actions to replace self-harm, such as intense exercise, a hot or ice bath, holding ice cubes, or marking the body with a red Magic Marker.
• Let the dust settle by waiting for the tirade to finish and pausing before responding.
• De-escalate by lowering the volume of your voice and controlling physical expressions.
• Refocus the confrontation to a related, positive area.
• Fight fair by refusing to retaliate with sensitive remarks or dismissing anger as illness or hormones.
• Stay safe by leaving the scene if there is any risk of physical violence.
• Procrastinate productively by stalling rather than committing to high-emotion demands immediately.
• Establish more consistency by gently illuminating contradictory attitudes.
• Neither a hero nor a scapegoat be; accept positive idealizing without debate and avoid promoter or villain roles.
• Take responsibility but challenge unreasonable vilification by stating facts without being defensive.
• Prepare for confrontations by anticipating responses and practicing reactions.
• Explain the no-win dilemma using SET as a tool.
• Deflect potential no-win domains by asking your partner's stance first.
• Use paradox to stimulate contrariness and independent motivation.
• Join a team or group activity to promote social interaction and define identity.
• Be positive, consistent, and present as a reliable source.
• Predict upcoming destructive patterns neutrally and pair predictions with Support statements.
• Walk the individual through the likely results of their behavior.
• Be part of a routine by arranging healthy activities to do together.
• Focus on the anger and self-hatred rather than pleading against the behavior.

What Not to Say

Because borderline individuals are extremely sensitive to words, minimizing their experience triggers defensive outbursts. Credibility is essential, meaning partners must remain accountable and honest.

• Avoid derogatory phrases like Don't be silly! or That's crazy.
• Avoid demeaning or directly contradictory expressions like You're overreacting.
• Don't deny your responsibility or try to shift the blame back onto them.
• Don't lie; maintain transparency and credibility.
• Eventually let it go rather than continuously plowing the same ground.
• Be careful with humor, as lighthearted kidding is often misinterpreted as humiliating ridicule.

7. Psychotherapy and Professional Treatment

Psychotherapy serves as the primary treatment for borderline personality disorder. You build insight, form a therapeutic alliance, and work toward effective and independent functioning.

Psychotherapy is the primary treatment for borderline personality disorder, focusing on developing insight, building a therapeutic alliance, and achieving more effective and independent functioning.

Treatment combines psychodynamic and cognitive behavioral approaches to rework old reflexes. The ultimate goal is for the therapist to work toward losing you as you gain autonomy.

Dr. Kreisman describes treating Julie, a 25-year-old law student. She cycled through intense relationships, experienced unremitting depression, and eventually required hospitalization before learning to accept herself and survive loneliness without self-harm.

How Psychotherapy Works

Transference involves projecting past emotional distortions onto the therapist. You frequently shift between seeing the provider as all-caring and all-deceitful.

Because you crave yet fear emotional closeness, you often test therapist boundaries. As the provider remains steadfast and consistent, you gradually develop object constancy and learn to trust.

The single factor most consistently correlating with therapeutic improvement is fit. Both parties must tolerate turbulence while maintaining a sturdy alliance.

When you evaluate a therapist, consider several specific points:

• Consider whether you are comfortable with the personality and style, ensuring they are neither too intimidating nor too seductive.
• Determine if the assessment and goals coincide with your own expectations.
• Evaluate whether the recommended methods, including psychotherapy type and meeting frequency, are acceptable to you.

Alternative Therapies

Group therapy provides a living laboratory to dilute intense individual attachments. You practice new social patterns and receive peer challenges.

Peers can challenge egocentrism and abrasiveness better than an idealized therapist. Lower-functioning patients often resist group settings due to envy, distrust, and fear of closeness.

Elaine, a 29-year-old woman abused by her father, initially used group therapy to act as a helper and deny her own issues. She eventually confronted her disdain for women and her transferred anger.

Hospitalization provides a structured milieu for managing acute crises and self-destructive impulses. Up to 20 percent of all hospitalized psychiatric patients are borderline individuals.

Patients often split hospital staff into all-good and all-bad roles. Acute admissions focus on short-term crisis resolution, while long-term hospitalization attempts deeper personality modification.

Jennifer spent months hiding in her bedroom closet during a long-term hospitalization before gradually engaging with her therapist. She eventually divorced her husband and obtained a professional degree.
