There’s a particular kind of exhausting that comes from being anxious in a relationship. Not anxious about the big things — the obvious problems you could point to and say, there, that’s why. Anxious in a low-level, persistent way when things are actually fine. Anxious when your partner is quiet, when a text takes too long to arrive, when they seem slightly elsewhere at dinner. Anxious in a way that you know, on some level, isn’t entirely rational — and that awareness makes it worse, because now you’re anxious about being anxious.
I hear this a lot in my work. “I know he loves me, but I can’t stop waiting for something to go wrong.” “She hasn’t done anything wrong and yet I’m constantly checking, constantly looking for signs.” “I ruin good things. I can feel myself doing it and I can’t stop.”
The first thing I want to say is that this isn’t a character flaw. It’s not proof that you’re too much, or broken, or fundamentally unsuited to a relationship. It’s a part of you that learned, somewhere along the way, that love is not safe — that the people who matter most are also the ones most able to hurt you, and that the only protection is vigilance.
That part isn’t wrong. It’s working from solid historical data. The problem is that it’s applying old information to a new situation, and in doing so it’s creating the very distance it’s trying to protect you from.
Relationship anxiety almost always has roots that predate the relationship you’re in. The person who grew up in a household where love was conditional — where affection arrived or disappeared based on behavior, mood, or circumstance — often develops a part that scans relationships constantly for early warning signs. Not because they want to. Because that part learned that the warning signs were real, and that missing them cost something. The person whose first serious relationship ended in betrayal carries a part that’s decided: trust is a liability. Keep some back. Always have one eye on the exit.
These parts aren’t pathological. They were smart adaptations to real situations. The trouble is they don’t automatically update when the situation changes. They keep running the old programme in the new relationship, and the new partner — who may be entirely trustworthy, entirely present, entirely not the person who caused the original wound — gets treated with the suspicion that belongs somewhere else entirely.
What this looks like in practice varies. Some people become hypervigilant — reading tone, watching body language, mentally cataloguing moments of distance as evidence of something coming. Some people become clingy in ways they can see but can’t stop, seeking reassurance that only lasts for a few hours before the need returns. Some people do the opposite — they shut down preemptively, keeping a part of themselves in reserve so that if it falls apart, they haven’t given everything. And some people, confusingly, create arguments. Pick fights. Push to see if the person will leave. Not because they want the relationship to end, but because the uncertainty of not knowing is worse than the certainty of a test.
If you’re the partner of someone living with this, the experience is often deeply confusing. You feel like you can never quite do enough. You give reassurance and it evaporates. You act consistently and it doesn’t seem to register. It’s not that your partner doesn’t believe you — there’s a part of them that does. It’s that another part doesn’t trust its own ability to read the situation, and so it keeps checking.
What shifts this isn’t more reassurance, and it isn’t the anxious person trying harder to control the anxiety through willpower. What shifts it is getting curious about the part that’s anxious — where it came from, what it learned, what it’s actually afraid of beneath the checking and the scanning and the low-level dread. In my work using Internal Family Systems therapy, we spend time getting to know that part properly. Not trying to silence it or argue it out of its position, but actually listening to it. Understanding its history. Acknowledging what it’s been trying to do for you. And gradually, as it feels heard rather than suppressed, it loosens its grip.
This is usually work that benefits from doing individually first — getting to know your own system, understanding which parts get activated in relationships and why — and then, if you’re in a partnership, bringing some of that understanding into the relationship itself. Because once your partner can see that the anxiety isn’t about them — that it’s a part of you responding to an old blueprint — the conversation between you changes. It becomes less about blame and defence and more about two people working out together how to create enough safety for that anxious part to finally stand down.
It takes time. These parts don’t shift overnight. But I’ve watched it happen consistently enough to say with confidence: relationship anxiety is workable. You don’t have to keep white-knuckling your way through good relationships, waiting for them to break.
