What Is BPD Splitting?
Splitting is a symptom of borderline personality disorder (BPD). BPD is a distinct and disruptive disorder that severely affects a person’s ability to regulate their emotions.
With BPD splitting, there is no middle ground. A person will view the nature of people and situations as either black-or-white or all-or-nothing.
An example is declaring a romantic interest "my future partner" but after the romantic interest is rebuffed, declaring "I wasn't interested anyway."
With BPD splitting, the turnaround is about more than just saving face—it’s an unconscious or unintentional reframing of how a person views a situation that turns uncomfortable or uncertain.
Splitting is an extreme behavior, interfering not only with relationships but with a person's sense of well-being.
Although people will sometimes casually claim that a person has a "borderline personality," BPD is more than just a personality trait. BPD is a mental health condition that is diagnosed based on specific criteria outlined in theDiagnostic andStatistical Manual of Mental Disorders (DSM-5).
Definition
Splitting is a defense mechanism in which a person goes between extremes of:
- Idealization(in which a person attributes exaggeratedly positive qualities to someone or something)
- Devaluation(in which a person attributes exaggeratedly negative qualities to someone or something)
Splitting is a normal behavior in younger children who are not yet able to grasp how complex relationships or situations are, and instead simply categorize them as being either “bad” or “good.” Splitting is a defense mechanism that helps children cope better.
However, if childhood development is disrupted by something like emotional trauma, a person may hold onto this defense mechanism as they grow up. As an adult, they will be unable to find a middle ground between idealization and devaluation.
Splitting can also occur in people living withnarcissistic personality disorder (NPD).
What Does Projecting in Psychology Mean?
Splitting in BPD: How Can You Tell?
BPD splitting is characterized by a rapid, extreme change in how a person or situation is perceived. The perception may go back and forth between "good" and "bad" or remain static once the altered perception is declared.
In the first situation, the switch is often referenced by the action of the other person.
For example, a person with BPD might say that a person “finally came to their senses" or "I finally found out the truth about” a person, rather than considering whether the change in their perception of this person might have been unreasonable.
In the second situation, a person with BPD may idealize a person only to devalue them and never go back. This inflexibility may serve as proof that the decision was "right" or even righteous.
Other signs of BPD splitting include:
- Habitually making snap judgments about people or situations
- Having absolute certainty that the perception is not correct
- Rapidly switching to the polar opposite view with the same level of certainty
- Craving attention and needing frequent reassurance from idealized people
- Punishing idealized people who do not give them the attention or reassurances they seek (e.g., with angry outbursts or the silent treatment)
- Describing things in absolutes (e.g., “they never do anything right”, “they always do things to perfection")
- Using extreme words to describe people or situations (e.g.,"angelic" or "evil," "genius" or "moron," or "ravishing" or "hideous")
- Expecting others to choose sides when a person or situation is devalued
- Shutting down or feeling attacked when others don't share those perceptions
Triggersfor BPD Splitting
Splitting is triggered by anything that causes a person with BPD to take an extreme emotional viewpoint.
The trigger could be something that seems harmless or “innocent” but is enough to spur emotions that a person with BPD is not able to handle.
Thetriggersfor splitting with BPD are more or less the same as those for children or people with NPD. Splitting is a defense mechanism used to counter emotions a person with BPD cannot control.
Splitting is a way of avoiding, deflecting, or sidestepping the feelings that are a big part of living with BPD, including:
- A low or unstable self-image
- Chronic feelings of emptiness
- A lack of self-direction, ambitions, or goals
- A general lack of empathy for others
- Hypersensitivity and constantly feeling insulted
- Impulsivity and acting without thought to positive or negative things
- Risk-taking when distressed without regard for the consequences
- Intense but unstable relationships marked by mistrust
- A preoccupation with unpleasant experiences in the past or the possibility of negative ones in the future
Any event or action that triggers these emotions— whether it’s perceived or real—can trigger splitting in someone living with BPD.
BPD Splitting and Relationships
Splitting can cause distress in relationships for people with BPD and their loved ones in a few ways:
- It can cause stress related to the constant need for reassurance.
- It can lead tocodependencybetween the person with BPD and the person they think is “perfect.”
- It can leave the idealized partner on edge if they feel mistrust or worry that the person with BPD could suddenly change their opinion of them.
- It can make a person with BPD vulnerable to harm if they are unable to see warning signs of danger in a person that they believe is infallible.
How Long Do BPD Relationships Last?
How long relationships last is different for every person living with BPD.
Some people have relationships that just last a few weeks or months, while other people living with BPD have relationships that last years or even decades, though, the relationship may have cycled through periods of breaking up and getting back together.
A small 2014 study on groups of women living with BPD looked at how long their relationships were, on average.
In the first group, the women were all married or living with a partner. The average length of their relationship was about 7 years.
In the second group, the average length of a relationship for women living with BPD who were married was about 4 years and about 2 years for people who were not married.
While the study did look at how long BPD relationships lasted on average, it was limited because it used different groups of patients and most of the patients included were White women. So, it’s not clear how well these averages reflect the experiences of other people living with BPD.
Treatment
There is no specific treatment for BPD splitting. Splitting is addressed as part of a treatment plan for BPD that involvespsychotherapyand sometimes medication. In severe cases, inpatient treatment for care under apsychiatrist is needed.
Types of psychotherapy that can help people with BPD splitting include:
- Dialectical behavior therapy (DBT): Used to help people regulate emotional responses
- Mentalization-based treatment (MBT): Used to help people recognize how thoughts and feelings are linked to behaviors
- Group therapy: Used to help people learn to interact with others with empathy and gain awareness of their responses
- Transference-focused psychotherapy (TFP): Uses a person's split-off emotional parts.
Some people with BPD take medications to help them manage the condition, such asantidepressants.antipsychotics,anxiolytics(anti-anxiety drugs), andmood stabilizers.
How Borderline Personality Disorder Is Treated
Summary
BPD splitting is a symptom of borderline personality disorder (BPD). It’s when a person sees everything as black or white, good or bad, or best or worst. Splitting is a defense mechanism people living with BPD use to deal with emotions (such as the fear of abandonment) that they cannot handle.
Instead of working with the complexities of relationships and situations, a person with BPD splitting either sees them as all good (idealizes) or all bad (devalues).
Helping people with splitting is part of a BPD treatment plan that usually involves psychotherapy and sometimes medications.
Splitting can feel overwhelming both for the person with BPD and those who love them. With time and the appropriate treatment, people with BPD can reduce the severity of their symptoms and lessen the negative impact splitting has on their relationships and lives.
