I'll start by saying I feel quite anxious about this, so please be gentle. It's been suggested by a therapist that I have CPTSD. My childhood could in some ways have had this effect, as it was quite frightening/ unstable/ volatile and some abuse. CPTSD does also explain a lot of things my partner and I have been struggling with, e.g. sometimes during an argument I will 'switch off', stop being able to speak in a genuine way, talk really robotically, move more slowly, get a bit glazed over/ glassy eyed. It sort of looks like 'silent treatment', but - I really hope I can be believed here - I absolutely do not intend to do it, I just switch into this state, and when it switches off again I sometimes can't really remember what's happened, what I've said etc. The therapist says this is 'dissociation'. I also self-harm regularly, every few days/ at least once a week, which my partner knows about but no one else.
All that is sort of the background, to show that I am not an easy person to be in a relationship with. I struggle with conflict, and have very unhealthy and probably frightening coping mechanisms - have had to go to hospital a few times due to self harm.
This is all extremely stressful and frustrating for my partner. However, he has increasingly started getting very angry in arguments: he broke the door to our bedroom when I'd retreated in there during an argument, and also kicked the bathroom door trying to break it open when I locked myself in there during another argument. He's called me a bitch and also a c*. He's said it's awful being with me, and he wants to separate - though after things have calmed down he says that he doesn't mean this.
My question is, how do we get out of this pattern? Does anyone have experience of CPTSD and a relationship where you don't end up afraid of your partner? I think, because fear was 'normal' for me, I think I'm provoking my partner until he behaves in the frightening way that I see as 'normal'. But now, I feel afraid all the time. And that's very frustrating for him, because these outbursts are absolutely not his normal at all. He's very kind and generous and we have a lot of fun together normally.
Please don't tell me to leave. I have no where else to go anyway, and he is a really good person. I won't be leaving him, so this response even though I appreciate it will be well-meant, just won't help me.
