Borderline personality disorder (BPD) is a mental health condition that shapes how people see themselves and others. When people with BPD face an uncomfortable or overwhelming situation, they may engage in BPD love bombing and splitting. BPD splitting is an unconscious thought pattern that causes people to see things from a black-and-white perspective.
Learn more about splitting in BPD here. We’re discussing what this defense mechanism truly means, symptoms and triggers to be aware of, its impact on life and relationships, and how you can cope. There is hope even if you or a loved one is living with BPD and using splitting. With the right tools and support, you can learn to manage and overcome the negative impacts of BPD splitting.
Splitting behavior is a defense mechanism that allows people with types of BPD to reframe something in black-and-white terms. It’s called splitting because it involves putting people, places, and things into one of two categories. Splitting can cause people to view something as entirely good or completely bad.
While most people with BPD understand that the world is complex, splitting behavior can cause them to shift rapidly between two extremes. For example, someone with BPD may think that another person is amazing one day, only to see them as the worst person in the world the next. This sudden shift generally occurs after a negative interaction — even if the exchange is brief. In one moment, they feel confident in the relationship, then they’ll suddenly view the person as worthless as soon as they make a mistake.
A splitting episode can also be a way for people with BPD to push blame on someone else. For example, if they forget to complete a task, they might insist it was stupid or that the instructions they received weren’t clear. At times, people with BPD may openly share these views with others, but splitting can also be an internal behavior.
Since splitting is an unconscious defense mechanism, people often find it hard to recognize when they engage in the behavior. Recognizing the signs of splitting can make addressing and changing behavior easier.
Common splitting borderline personality disorder symptoms include:
Any situation that causes an emotional reaction can be a trigger for splitting. People with borderline personality disorder frequently struggle with emotional regulation, and splitting can be a way for them to counter feelings that they’re unable to control.
Some splitting borderline personality disorder triggers include:
“Borderline personality disorder (BPD) splitting is a coping strategy often used by individuals with BPD to help them deal with stressful situations. They do this by identifying a person, place, or thing as either all good or all bad. This can be triggered when the individual is in an uncomfortable situation or meeting a new person. Reframing their thoughts allows them to cope more effectively in the moment. This is ultimately not a healthy way to deal with issues, and in therapy, they can find more effective ways to cope with their stress.”

Splitting in borderline personality disorder can lead to instability. The changes that splitting brings on can be intense. BPD leads to impulsive or reckless behavior, and when coupled with splitting as a defense mechanism, it makes it incredibly difficult — or even impossible — to build secure relationships.
“The impact of splitting includes having less meaningful romantic relationships or friendships. The individual might struggle with having inconsistent or negative relationships. Therapy can be a way for individuals with BPD to work on their relationships in a healthy way, so they avoid splitting.”

Not only can splitting make it hard to form relationships, but it also makes them difficult to maintain. Splitting can cause significant distress to both parties. It’s common to shift from idealization to devaluation quickly, which can lead to a long string of brief relationships. When relationships do last, it often leads to codependency.
Even though splitting is a defense mechanism, it can cause significant damage to relationships and a splitter’s well-being. Learning to cope with this BPD symptom can help people avoid instability and find balance in their life.
When you’re aware of splitting, you can take steps to break the cycle of behavior. Tracking your behavior can help you see unhealthy patterns. If you can identify your triggers, you can spot splitting when it occurs.
Stress and anxiety can lead to splitting episodes. If you’re able to calm yourself when you’re feeling overwhelmed, you may be able to avoid splitting. Breathing exercises and meditation could help you to relax before your emotions take over.
