Part 1 of 3: Between light and shadow - relationship between two borderliners
introduction
A relationship between two people with borderline personality disorder (BPS) is often intense, passionate, emotional – and above all challenging. Both partners struggle every day with inner insecurity, strong emotional fluctuations and deep-rooted fears, which can turn every everyday situation into a test of tears. But precisely because both partners deal with similar problems, there is also an extraordinary opportunity in such a connection: Understanding and healing through shared experiences.
But for this possibility to be used, it requires a lot of awareness, mutual understanding and a clear orientation about what constitutes a healthy and stable relationship.
Emotional instability in everyday life: The daily ups and downs
A typical feature of borderline is a pronounced emotional instability, which is mainly manifested by intense mood swings. Both partners often feel overwhelmed by their emotions, which can alternate abruptly between euphoria and deepest despair.
An everyday example: In the morning, you two wake up happily together. But suddenly a seemingly harmless sentence such as: ‘Today I am still on the road for a short time after work’ to trigger an enormous fear of loss. Concerns such as ‘He doesn’t love me anymore!’ or ‘She must have met someone else!’ begin immediately. The beautiful morning is destroyed, harmony becomes strife and chaos.
These sudden emotional turns make it difficult to build trust and security in the relationship, as any seemingly harmless situation carries the potential for escalation.
Understand and manage outbursts of anger
Outbursts of anger are a common reaction among borderline personalities, especially when fear or helplessness is felt. Anger often serves as an outlet for deeper feelings of abandonment, inferiority, or loss of control.
Typical forms of an outburst of anger can be:
- Screaming and verbal aggression
- Insults and derogatory remarks
- Destroying Items
- Impulsive behaviour (e.g. sudden separation or self-harm)
Practical example: A delayed response to a message is already enough to arouse panicked feelings of loss. Out of fear arises anger, and out of anger an emotional attack: “You are constantly ignoring me! You don't care about me!” – although the other may have just been in the meeting or in traffic jams.
How can you handle it?
- Communicate early when anger arises (‘I just notice how I get angry, give me space for a moment.’)
- Make clear arrangements on how to react at critical moments (“If you get angry, give me a sign so I know you are fighting”).
Anxiety: The Permanent Companion
Fear is one of the dominant feelings in relationships between borderliners. Constant worry about leaving or being rejected can seriously affect everyday life.
Frequent fears are:
- “I am not adorable.”
- “My partner will leave me soon.”
- ‘If he/she knows me correctly, I will be rejected.’
Typical situations:
- When the partner is traveling with friends, fears and mistrust arise: “Am I no longer important to him?”
- A brief moment of silence during a conversation immediately triggers the question: ‘Has he or she lost interest?’
These fears often prevent both partners from enjoying the relationship, and often lead to irrational conflicts or jealousy attacks.
Self-injury: Why does he/she do this to himself/herself?
Self-harm is a way for many borderliners to cope with unbearable feelings. It is not manipulation, but a desperate attempt to alleviate emotional pain or regain control of oneself.
Forms of self-harm:
- Cutting, cracking
- Burning or scalding
- Use of drugs or alcohol
- Extreme withdrawal and self-isolation
Example: After a violent dispute, a partner withdrew. When he reappears, the other discovers fresh injuries. The response can range from helplessness to anger (‘Why are you doing this?’), which in turn provides further conflict material.
Here it is important not to take the injuries personally, but to see them as a clear signal that the emotional overload is currently very high.
First practical exercises for your everyday relationship
So that your relationship isn't just crisis management, here are some practical ways to strengthen your connection:
1. Daily emotional check-in
Sit down daily and talk briefly about your current mood and state of mind. This way you avoid misunderstandings.
2. The traffic light system
Arrange a traffic light system to make your current emotional resilience clear:
- Green: All right, I feel stable.
- Yellow: I can feel emotions boiling up. I need some rest.
- Red: I'm totally overwhelmed. I urgently need some distance.
This system makes it easier for you to communicate quickly and clearly.
Part 2 of 3: Typical misunderstandings and the art of self-care
In a relationship between two borderliners, misunderstandings and emotional entanglements are particularly common. Both partners interpret each other's behavior through the filter of their own fears and insecurities, which quickly leads to conflict. Here it is important to know typical stumbling blocks and to learn to counteract them consciously.
Common misconceptions between borderliners
Misunderstanding 1: “If he/she really loves me, he/she should know how I feel.”
In relationships between borderliners, it is often assumed that the partner must be able to instinctively recognize feelings and needs. This leads to needs not being clearly communicated – and frustration because the other does not seem to respond.
Example: A partner feels lonely, but does not express this clearly. The other spends time with friends. The feeling arises: ‘I don’t care’, although there was simply a lack of communication.
Solution: Learn to communicate clearly and directly. No one can read thoughts – even the most sensitive partner cannot. Openly address your needs and fears.
Misunderstanding 2: ‘Criticism always means rejection.’
Borderliners are sensitive to criticism because it is immediately equated with rejection or loss. A small suggestion for improvement can trigger an intense emotional crisis.
Example: ‘Can you please let me know in time next time you come later?’
This is often perceived as a deep attack: “I'm not good enough for you!”
Solution: Together, practice distinguishing constructive criticism from personal rejection. Reassure each other that your love is not endangered by factual cues.
Misunderstanding 3: ‘He/she avoids me because I am not adorable.’
When one partner withdraws, the other immediately interprets it personally. Withdrawal is rarely understood as a need for self-protection, but almost always experienced as a personal rejection.
Example: After a fight, a partner retreats to the bedroom to calm his emotions. The other immediately interprets this as deprivation of love.
Solution: Communicate clearly when you need space ("I need a little time for myself. It's not up to you). The other should learn to accept this withdrawal not as an attack, but as a necessary pause.
Why self-care is crucial for both partners
Self-care is not selfish, but necessary for survival – especially in an emotionally demanding relationship. Those who take good care of themselves have more strength and clarity to respond to their partner.
Important aspects of self-care:
- Taking emotional breaks
Consciously take time out on a regular basis to focus on yourself.
Example: Walks, meditation, sports, listening to music.
- Setting Healthy Limits
Learn to say no when something becomes too stressful. Communicate your boundaries calmly and firmly.
- Use professional support
Therapy, self-help groups or counselling offer spaces to reflect one's own feelings and needs without burdening the partner.
Example of good self-care:
“I just realize that I am overwhelmed. I'm going for an hour's walk to find myself again. After that, we will continue to talk calmly.”
Self-care means taking responsibility for one’s emotional stability – an essential key to a stable relationship.
Detect warning signals and act early
In relationships between borderliners, there are clear warning signs that the relationship is moving in a dangerous direction. Taking these signals seriously and counteracting them in time protects against serious crises.
Warning signal 1: Increasing isolation
You withdraw more and more as a couple, hardly meet any friends or family, and only revolve around your own emotional problems.
Solution:
Make conscious contact with the outside, even if it is difficult. Get external perspectives from friends, family, or therapists.
Warning signal 2: Frequent, intense escalations
If disputes escalate more and more frequently, verbal or even physical violence occurs, external help is urgently needed.
Solution:
Sets clear emergency rules (‘As soon as violence threatens, we immediately leave the situation.’). Use professional support to break these destructive patterns permanently.
Warning signal 3: Constant control and mistrust
When each step of the partner is controlled (mobile phone, social media, contacts), the relationship has become toxic.
Solution:
Communicate clearly and clearly boundaries, get external support. Trust can only be rebuilt through openness and honesty, not through control.
Checklist: When do you urgently need external support?
- Violence or threats occur.
- Self-injury is increasing sharply.
- Suicidal thoughts are expressed.
- Massive isolation and discontinuation of social contacts.
- Persistent mistrust and compulsion to control determine the relationship.
In these cases, professional help should be sought urgently.

💡 More practical exercises for your everyday life
These exercises help you to increase your emotional stability in the long term:
Exercise 1: The emotional letter
- Write each other regular letters expressing your feelings. Letters often allow for more honest communication than direct conversations.
Exercise 2: The Positive Treasure Box
- Keep a small notebook in which you write something positive about your partner every day. In case of conflict, read from it – this will help you not to slip into a negative spiral.
Exercise 3: Relaxation rituals
- Develop simple relaxation rituals together (e.g. joint meditation, yoga or breathing exercises) in order to reduce emotional tensions together.
🌱 Conclusion: Growing Together Despite (and Because of) Borderline
Yes, a relationship between two people with borderline personality disorder is enormously challenging. But it also offers a unique opportunity:
You can grow together because you understand each other like no one else. You both know what it means to fight inside. You both know the feeling of deep loneliness, but also the longing for real closeness and connection.
That is why together you can find a way that is healing and empowering for both of you, provided you are willing to invest the necessary work. Use your experiences to support each other, but never forget that each of you is responsible for your feelings and well-being.
You're not your fault. You are two people who, through their mutual understanding and deep connection, have the opportunity to build a particularly intense and meaningful relationship.
Never forget:
- Every conscious decision for understanding is a small victory.
- Every conflict you resolve constructively brings you closer together.
- Each day that you consciously design with each other strengthens your common ground.
Borderline does not mean the end of a stable relationship – it offers an opportunity to grow beyond the ordinary. For you are not weak, but enormously strong. You have already proven how resilient you are.
Now it is time to transform your strength into growth and connectedness together.
🌟 Closing word: A little letter to both of you
Dear readers, dear readers,
You may have wondered sometimes if your relationship really has a future. You may sometimes doubt whether it will ever be easier. I want to promise you one thing:
Yes, it can be easier – but never on its own. It gets easier because you learn to grow together. It gets easier because you learn to understand each other better. And it becomes easier because you learn to accept and love yourself, despite or precisely because of all the challenges.
Be patient with each other and above all with yourself. Because in patience and the willingness to develop together lies the true power of your relationship. You are not alone on this path.
Believe in each other, do not give up, and never forget: You are stronger than you believe. You can do something wonderful together.
Lots of strength, courage and love on your journey together!
