When someone with borderline personality disorder pushes you away, they are usually acting on intense fear, not a genuine desire to end the relationship. The pushing can look like sudden coldness, picking fights over nothing, ignoring your calls, or telling you they don’t need you anymore. Your instinct might be to either chase harder or walk away for good, but neither extreme tends to help. What works is a steadier, more informed response that protects both of you.
Why Pushing Away Happens
BPD involves a persistent pattern of unstable relationships, an unstable sense of self, and intense emotional swings. One of its core features is a desperate effort to avoid abandonment, whether real or imagined. That might sound contradictory: why would someone terrified of being left push you away? The answer lies in two competing fears operating at the same time.
The first is fear of abandonment. A person with BPD can interpret small signals, like a cancelled plan or a delayed text, as evidence that you’re about to leave. That interpretation triggers panic or rage that feels completely real to them. The second is fear of engulfment, the sense that closeness itself is threatening because it means losing their identity or becoming too vulnerable. As a relationship deepens and intimacy grows, this fear can intensify until the person feels they need to create distance to survive emotionally.
These two fears create a push-pull cycle. The person draws you in during periods of idealization (you’re perfect, irreplaceable), then flips into devaluation (you’re the problem, you never cared) when closeness triggers their fear of engulfment or when they perceive a threat of abandonment. This shift is called splitting: black-and-white thinking where someone is seen as all good or all bad, with very little middle ground. Splitting is a defense mechanism. It helps the person manage emotions that feel intolerable, but it can be deeply confusing and painful for the people on the receiving end.
What It Feels Like for You
If you’re searching for this, you’re probably already exhausted. Research on caregivers and loved ones of people with BPD shows the emotional toll is significant. A systematic review published in the Harvard Review of Psychiatry found that partners and family members of people with BPD scored higher on measures of burden than caregivers of people with mood disorders, psychotic disorders, and substance use disorders. Their average depression scores landed well above the clinical threshold for depression, at levels notably higher than those seen in caregivers of people with schizophrenia or major affective disorders.
Grief was also elevated. Loved ones reported mourning the relationship they thought they had or the person they thought they knew. That feeling of loss while the person is still in your life is disorienting, and it’s common. You are not weak for struggling with this. The emotional weight is real, measurable, and well-documented.
What Not to Do
A few natural reactions tend to make the cycle worse:
- Chasing and reassuring frantically. When you flood someone mid-episode with texts, apologies, or desperate pleas, it can confirm their unconscious belief that the relationship is unstable and high-stakes. It can also feel engulfing, which pushes them further away.
- Retaliating or punishing. Getting cold in return, threatening to leave, or giving a taste of their own medicine feeds directly into their fear of abandonment and can escalate the situation dramatically.
- Taking the bait on content. During devaluation, the specific complaints (“you never listen,” “you don’t really love me”) often aren’t about the stated issue. Arguing the details of the accusation usually leads nowhere because the real driver is emotional flooding, not a factual disagreement.
- Abandoning your own needs entirely. Becoming so focused on managing the other person’s emotions that you stop eating, sleeping, seeing friends, or going to work puts you in a position where you can’t help anyone, including yourself.
Stay Calm and Stay Present
The most effective thing you can do in the moment is remain steady. That doesn’t mean emotionless or robotic. It means you don’t mirror the intensity. If they escalate, you keep your voice even. If they say something designed to provoke, you acknowledge the emotion without matching it. Something like “I can see you’re really hurting right now, and I’m not going anywhere” communicates safety without chasing.
You don’t need to solve the episode. You’re not their therapist, and trying to be one usually backfires. What you can offer is predictability: the same tone, the same presence, the same calm response each time. Over time, consistency is one of the most powerful things you can provide because it gradually challenges the belief that everyone will eventually leave or hurt them.
If the person needs physical space, give it. Let them know you’re available when they’re ready, then step back. Hovering communicates anxiety, not love, to someone in that state.
Set Boundaries That Protect You
Boundaries are not punishments or ultimatums. They are decisions about what you will and won’t accept in your life, paired with actions you’ll take if those limits are crossed. The key distinction: boundaries are about your behavior, not about controlling theirs.
A well-constructed boundary has two parts. The limit (what behavior you won’t tolerate) and the consequence (what you will do if it happens). The consequence is something you control entirely.
Some practical examples:
- Yelling or name-calling: “If someone yells at me or calls me names, I will leave the room and we can talk when things are calmer.”
- Silent treatment: “If you’re not ready to talk, I’ll ask once what’s going on. After that, I’ll go about my day and we can reconnect when you’re ready.”
- Repeated late-night crisis texts: “I care about you, and I’ll respond to messages during waking hours. If it’s an emergency, here’s a crisis line number.”
Notice that none of these say “you need to stop doing X.” They say what you will do. That’s the difference between a boundary and an attempt to control someone else. You follow through every time, calmly and without drama. Inconsistent enforcement teaches the person that your limits aren’t real, which makes future boundary-setting harder.
Expect pushback. Boundaries can initially feel like rejection to someone with BPD, which means the pushing-away behavior may temporarily intensify. That’s not evidence the boundary was wrong. It’s evidence it was needed.
How Long Episodes Last
There’s no clean, universal timeline for how long a devaluation episode lasts. Splitting can shift rapidly, sometimes within hours, sometimes stretching over days or weeks. The severity, the specific triggers, whether the person is in therapy, and whether the environment around them is stable all play a role.
What’s more useful than predicting a timeline is recognizing the pattern. Over time, you’ll likely notice that certain situations trigger the push (increased intimacy, a perceived slight, stress at work, a change in routine). Understanding those triggers helps you anticipate episodes and respond rather than react. It also helps you depersonalize the behavior, which is essential for your own mental health.
Protect Your Own Mental Health
Loving someone with BPD requires a sustained emotional output that can quietly erode your wellbeing. The research is clear that caregivers in this situation carry depression, grief, and burnout at rates higher than those seen in almost any other caregiving context. That means taking care of yourself isn’t optional or selfish. It’s structural.
Individual therapy for you, not just for the person with BPD, is one of the most useful steps you can take. A therapist who understands personality disorders can help you identify when you’re absorbing emotions that aren’t yours, when guilt is driving your decisions, and when your boundaries are slipping. Support groups, both in-person and online, can also reduce the isolation that comes from loving someone whose behavior is hard to explain to friends and family.
Maintain your own friendships, hobbies, and routines. These aren’t luxuries. They’re the scaffolding that keeps you stable enough to be present in the relationship without losing yourself. If you notice that your entire emotional life revolves around the other person’s mood, that’s a signal to pull back and invest in your own foundation.
When the Person Is in Treatment
BPD is one of the more treatable personality disorders when the person engages in specialized therapy. If your loved one is working with a professional, the pushing-away episodes may become less intense and less frequent over time. Your role during treatment is to stay consistent, reinforce the skills they’re learning, and resist the urge to “fix” things yourself.
If they’re not in treatment, you can express that you think it would help, but you can’t force it. What you can control is whether you’re getting support, whether your boundaries are in place, and whether the relationship is sustainable for you in its current form. Loving someone does not obligate you to endure harm indefinitely, and recognizing your own limits is not abandonment.
