Understanding Borderline Personality Disorder (BPD)
If someone you love has Borderline Personality Disorder (BPD), you may sometimes find yourself confused by their reactions, emotions or behaviour. You may wonder why something that seems small to you can become extremely painful or overwhelming for them, or why the relationship can sometimes feel very close and then suddenly very difficult.
Learning a little about BPD can help make some of these experiences easier to understand.
What is Borderline Personality Disorder (BPD)?
What is BPD?
Borderline Personality Disorder is a mental health condition that can affect the way a person experiences emotions, relationships and their sense of themselves.
One of the central difficulties is emotional regulation. A person with BPD may experience emotions very intensely and may find it difficult to settle or return to a calmer emotional state once they have been triggered.
This doesn't mean that their feelings aren't real. Their emotional experience can be very real and very powerful, even when the situation may look quite different from the outside.
People with BPD can experience some of the following:
Not everyone with BPD experiences all of these difficulties, and BPD can look very different from one person to another.
Understanding the fear of abandonment
One of the most important things to understand about BPD is that the fear of abandonment can be extremely intense.
A delayed message, an argument, someone needing space, or a change in plans may sometimes be experienced as much more than the event itself. It can activate a much deeper fear:
When this happens, the person's emotional response can become very strong very quickly.
This can be difficult for a partner to understand, particularly when you are thinking about the situation logically and they are experiencing it emotionally.
When emotions become overwhelming
When someone is highly emotionally activated, their ability to think calmly, problem-solve and consider another person's perspective can temporarily become much more difficult.
It can help to think of it as being emotionally flooded.
At that moment, trying to prove that they are wrong or explaining why they shouldn't feel the way they do may not help. The first need may be to feel heard and emotionally safe.
This does not mean agreeing with everything they say or accepting behaviour that is hurtful or inappropriate.
It means recognising the difference between:
Understanding someone's feelings
and
Agreeing with their behaviour.
You can do one without doing the other.
BPD does not mean someone is deliberately difficult
It can be tempting for partners to think:
"They're doing this to manipulate me."
Sometimes behaviour can certainly feel manipulative, particularly when emotions are intense. However, it can be more helpful to understand that many behaviours associated with BPD develop as attempts to manage overwhelming emotional pain, fear or insecurity.
That doesn't mean harmful behaviour should be excused.
A diagnosis can help explain behaviour, but it does not remove responsibility for behaviour.
Healthy relationships still require respect, boundaries, accountability and a willingness to work on patterns that are causing harm.
A diagnosis can help explain behaviour, but it does not remove responsibility for behaviour.
What can help a partner?
If you are in a relationship with someone who has BPD, some things that can be helpful include:
Listen before trying to fix.
Sometimes being heard is more helpful than immediately offering solutions.
Validate the emotion, not necessarily the behaviour.
You might say, "I can see that this has really hurt you" without saying, "You're right about everything that happened."
Stay calm where possible.
When one person's emotional intensity rises, the other person's calmness can sometimes help prevent the situation from escalating.
Be clear and consistent.
Mixed messages can sometimes increase uncertainty and anxiety.
Have healthy boundaries.
Caring about someone does not mean accepting yelling, threats, intimidation, insults or other behaviour that is harmful.
Look after yourself too.
Being close to someone experiencing intense emotional difficulties can be exhausting. Your own emotional wellbeing matters.
Treatment can help
BPD is treatable. Many people with BPD make significant improvements with appropriate support and therapy.
One of the therapies with strong evidence for BPD is Dialectical Behaviour Therapy (DBT). DBT helps people develop skills for managing intense emotions, tolerating distress, improving relationships and responding to difficult situations in healthier ways.
Other therapeutic approaches can also be helpful.
Recovery does not mean that a person will never experience intense emotions again. It can mean developing greater awareness, stronger emotional regulation skills and healthier ways of responding to difficult feelings and relationship situations.
If you are the partner
Being in a relationship with someone experiencing BPD can be confusing and emotionally exhausting.
You may find yourself questioning what happened, wondering whether you could have handled things differently, or feeling responsible for your partner's emotional wellbeing.
It is important to remember:
You can care deeply about someone without being responsible for regulating their emotions.
You can have compassion for what someone is experiencing while also recognising the impact their behaviour may have had on you.
And if a relationship has ended, it is completely understandable to experience grief, confusion, anger, guilt and a strong desire to understand what happened.
Learning about BPD isn't about deciding who was right or wrong.
It is about gaining a clearer understanding of the emotional patterns that may have been present, while also making space for your own experience, your own feelings and your own healing.
