Unreg for this... not sure what to do, need some advice
I've been with my partner for almost 6 years, we had quite a turbulent start to our relationship which was long-distance to start off (3 hour drive), then around 4 years ago I moved in with him with my daughter. Living together really was a disaster and around 2.5 years ago we moved out to a place of our own nearby. I know this wouldn't necessarily be conventional but it really worked for us and our relationship has been pretty good since then, a few ups and downs naturally but we've been very happy in general.
He has a lot of issues from his past, mostly around abandonment (adopted) and a very abusive (adopted) father as well as the death of both his (adopted) siblings, I have issues of my own mostly around serious physical abuse and some sexual abuse from childhood as well as a failed marriage. We also had a miscarriage early on in the relationship.
I've done many years of counselling, therapy & healing on myself and in a good place now or so I thought.
I recently moved house again, same town and though it's a really good move for me and my daughter it seems to have brought up a lot of old dark stuff for my partner, who also gave up cigarettes 2 weeks before hand! We had to move back in with him for around a week between moving out of one house & moving in to the new one- it was a TOTAL DISASTER, all the old stuff of living together came back up again even though we've stayed with him during the time previously without any serious problems.
When we moved out originally we moved to quite a small house and I had to leave quite a lot of stuff in his place which he didn't seem to mind but since moving he has become obsessed with me 'getting all my **** out of his house'.
I am quite happy to do that but all I asked for was a bit of time to unpack this new place first (we're here only a week yesterday- Wednesday), I also have quite a severe neck injury and am waiting for spinal surgery for the last 2.5 years, so on top of the stress of moving I am also in a great deal of pain, I take quite strong pain killers & have a pain patch.
He has been absolutely brilliant during the move, carrying and moving & driving but he's just been going on and on and on about me moving my other stuff from his house EVERY TIME we see each other or speak to each other... he said he would help but it was literally driving me insane, I begged him to give me some time but he wouldn't listen and eventually it came to a huge head & I told him I wanted to finish with him out of desperation mostly. I regretted it instantly.
Since then he has cut me off almost completely, I've tried explaining that I didn't mean it and I was sorry... we have both said it before at different times and the other knew it wasn't meant, he has also said some pretty horrible things to me in the past which I have forgiven him for.
I'm in absolute bits over this, I really love him & I don't want to lose him but I also know he acted really badly and was basically bullying me at a very vulnerable point in my life. This has brought up some really old dark feelings for me and I'm really not taking it very well at all, not sleeping, crying all the time... I can't stop thinking about it and I have a pain in my chest and stomach.
He won't answer my calls or texts apart from speaking yesterday to confirm I would go over on Saturday to basically clear the house out.
I got very emotional during this call and was looking for clarification, he kept saying that I was the one who finished it and now he's adjusting to that (I said I didn't mean it & explained why I said it) & at the end I asked him can you just answer me if we are finished or not and he said 'ok yeah it's over, whatever' or words to that effect...
It's been a week of hell... gone from chatting to my best friend a few times a day and seeing each other every day to next to nothing at all and he knows that this is killing me too

I'm living in a town far from close friends and family that I moved to basically to be with him, I know a good few people but mostly all of them through him and no-one I'm really close to.
