Have been together with DP for nearly 2 years. Just to about to move in together, I already have a lot of stuff moved, handed a notice on my flat two weeks ago (rented).
I'm moving to DP's rented flat too, 15 miles from where Iive. This is mainly to help him with contact with his DD whom he lives locally to, sees her nearly every day and does all pick ups/ drop offs.
I have started to have a feeling that I'm making a mistake. He can be disrespectful sometimes but always blames this on depression / anxiety (he is on meds and therapy). He says I don't have any empathy when I get angry about the way he speaks to me sometimes.
The last two weeks since I have handed the notice and started spending more time at his have been horrible. We used to spend loads of time together but it was never that bad. He is on a huff most of the time, ignoring me when not in a mood, accusing me I'm making problems out of nothing. Everyone is asking why is it me having to move out and when I said that to him he waived a middle finger and said 'fuck them all', ie my parents, siblings, friend.
On Thursday his DD was here. They planned to go for a meal yesterday. I didn't know anything until yesterday afternoon, basically was given half an hr to get rady and go. No one asked me if that's what I was planning but hey ho I thought, fine he is taking me out. The thing is I had to pay for the meal because, at the till he said it is my turn as he paid last time. I thought that was rude and you don't expect someone to pay for the meal where they didn't get any say in where / when we go? I asked him to transfer the money as this was cheeky of him and unfair but he refused and said I've told him I was going to pay the next time. I haven't.
I got up yesterday morning to find his DD (9) wearing my socks 
Because 'dad says I could'. She has been taking my stuff from unpacked bags, books, because 'daddy said I could'.
I feel like I don't have a control of my life any more. I feel like signing out of it compeletely and run away but I hear I'm over reacting when I raise anything. I feel like I can't trust my own judgment and don't know any more what I want. My head is a mess and I'm in a panic mode not knowing what to do. I don't deserve to be treated like that but he says it is either my fault or he blames depression /anxiety and says he can't help it.
I don't know what to do.
