Borderline Personality Disorder and Relationships

 

Borderline Personality Disorder (BPD), also called Emotionally Unstable Personality Disorder (EUPD), affects how people experience emotions, how they see themselves, and how they relate to others. Relationships are often at the centre of BPD – both as a source of comfort and as a source of pain. Many people with BPD long for close, secure relationships, but at the same time find them confusing, overwhelming, or frightening. This can lead to a cycle of closeness and conflict that feels exhausting for everyone involved.

​

Why Relationships Feel So Intense with BPD

 

People with BPD usually feel emotions more strongly and more quickly than others. A small change in tone of voice, a delay in a text message, or a cancelled plan can trigger feelings of rejection or abandonment. These feelings can be overwhelming and hard to manage, sometimes leading to sudden changes in mood or behaviour.

 

For example:

• A partner going quiet might feel like they are about to leave for good.

• A disagreement with a friend might feel like proof that the friendship is over.

• A new relationship might feel so exciting that it becomes all-consuming, only to swing quickly into fear or anger if things feel uncertain.

 

These reactions are not about being “too sensitive” or “difficult”. They are part of how BPD affects the brain and emotions. Understanding this can help reduce shame and make it easier to find healthier ways of coping.

Common Patterns in Relationships

 

1. Fear of Abandonment

 

One of the most painful parts of BPD is the deep fear of being left or rejected. Even small separations – like a partner going to work or a friend taking time for themselves – can feel unbearable. This fear can lead to behaviours such as:

• Constantly checking in or seeking reassurance.

• Struggling to trust that the other person really cares.

• Feeling panicked or angry if the other person seems distant.

 

2. “All or Nothing” Thinking

 

Relationships may swing between extremes. Someone might feel like their partner or friend is “perfect” one moment and then “terrible” the next. These sudden shifts are linked to emotional intensity and difficulties with seeing the “grey areas” in relationships.

 

3. Intense Connection, Followed by Conflict

 

It is common for relationships to start with great intensity. The closeness can feel exciting and comforting, but when difficulties arise, strong emotions may lead to arguments, withdrawal, or impulsive behaviours.

 

4. Identity and Self-Esteem Issues

 

Because BPD often involves uncertainty about one’s own identity, people may look to relationships to provide a sense of self-worth. This can create pressure on the relationship and make breakups or rejections feel devastating.

 

​

 

The Impact on Partners, Friends, and Family

 

It’s important to acknowledge that BPD doesn’t just affect the person who has it – it also affects the people close to them. Partners and family members may sometimes feel confused, drained, or even hurt. They might not understand why reactions are so strong, or why small disagreements escalate so quickly.

 

This doesn’t mean the person with BPD is “bad” or “toxic”. It means they are struggling with very real difficulties in regulating emotions and fears, often rooted in painful past experiences. With support and understanding, relationships can become healthier for everyone involved.

Building Healthier Relationships

 

Although relationships with BPD can be challenging, many people find ways to build stable, loving connections. Here are some strategies that may help:

 

1. Learn and Practise Communication Skills

• Try to express feelings calmly and clearly, rather than through anger or impulsive actions.

• Use “I feel” statements (e.g., “I feel anxious when I don’t hear back from you”) instead of blame (e.g., “You don’t care about me”).

• Pause before reacting if emotions feel overwhelming. Even taking a few minutes to breathe or step away can reduce conflict.

 

2. Build Awareness of Triggers

 

Notice what situations trigger strong emotions. Common triggers include:

• Feeling ignored or abandoned.

• Conflict or criticism.

• Changes in plans.

By recognising triggers, you can prepare healthier coping strategies instead of reacting automatically.

 

3. Practise Emotional Regulation

 

Therapies like DBT teach skills to manage emotions without letting them control your actions. Examples include:

• Mindfulness – staying in the present moment rather than jumping to conclusions.

• Distress tolerance – calming yourself with safe activities (music, exercise, writing) instead of harmful ones.

• Self-soothing – using comfort techniques like warm baths, blankets, or grounding exercises.

 

4. Create Healthy Boundaries

 

Boundaries are essential in relationships. This means respecting both your own needs and the other person’s needs. For example:

• Allowing space for each person to have time apart.

• Agreeing on what is acceptable in conflict (no shouting, no threats).

• Recognising when you need extra support beyond the relationship (such as therapy).

 

5. Strengthen Your Sense of Self

 

When you feel more secure in yourself, you don’t have to rely entirely on relationships for stability. Things that can help include:

• Developing hobbies and interests.

• Building friendships outside of romantic relationships.

• Working on self-compassion and positive self-talk.

​

6. Seek Professional Support

 

Therapies like DBT, MBT, or schema therapy can help you understand and change unhelpful patterns in relationships. Couples or family therapy may also help loved ones understand BPD better and improve communication.

Tips for Partners, Friends, and Family

 

If you love someone with BPD, here are some ways to support them while also taking care of yourself:

• Learn about BPD – understanding that behaviours come from fear and pain, not malice, can reduce frustration.

• Stay calm during crises – if possible, avoid shouting or walking away suddenly. Try to validate the person’s feelings without necessarily agreeing with everything they say.

• Set clear boundaries – this protects both you and the relationship.

• Look after your own wellbeing – supporting someone with BPD can be intense. Make sure you have your own support network and time for yourself.

• Encourage therapy and treatment – but try not to force it. Support works best when it feels like a choice.

Recovery and Hope in Relationships

 

Although BPD can make relationships difficult, recovery is absolutely possible. Many people with BPD learn to manage their emotions more effectively, reduce conflict, and build long-lasting partnerships and friendships.

 

Recovery does not mean becoming a “different person” – it means learning new skills, finding healthier ways to cope, and creating relationships that feel safer and more rewarding. With time, effort, and support, it is possible to move away from cycles of fear and conflict towards relationships built on trust, respect, and love.
