Advice Desperately Needed (Very Long)

I need some advice from an impartial 3rd party. Anyone that I could ask that I knkw would be bias in my favor automatically so I need someone who doesn't know me. Here it goes.

I have been with my current boyfriend for over a year and a half. In that time we have had a lot of ups and downs, including his ex being pregnant (turned put not to be his), both of us cheating, neither of us completely trusting the other although its gotten a little better. We decided back in the begining of the year we wpuld try for a baby. We both wanted it and talked about it and it was a mutual decision. I found out I was pregnant in August and we were both really excited.

Once the news broke that I was pregnant everyone waa excited but then I starteds that was noticing that things that were bothering me before were bothering me even worse now. Things I decided I didn't want my future child to see and think was okay. About a month and a half ago his grandpa died anf it was an emotional time for him. I didn't ignore that but at the same time I was going through terrible morning sickness and god awful migraines to where I wasn't keeping anything down. I should mention that his family lives in the same city we did and my family lives in another city 2 hours away. We always argued and got into and I broke down to my mom that I wanted to come home, and not just to visit. I blamed it on tje horomones even though that wasn't the whole truth. I did eventually have my dad come and get me and I stayed with my parents for a week. I missed his granddads funeral which he was reallt upset about with good reason. I didn't get back there in time to make it. When I did come back he was still angry with me. He didn't talk to me and whenever I would ask him something or say something I would get a short reply. We ended up getting into it again and he said he didnt even knkw why I came back, he didn't want me back there yet becaus he knew he was still angry with me. Well he gets angry a lot and says things that he means at the time but then feels better later. We argued and it was bad and he eventually left well we both did anc he ended up locking me out of the house. I don't think on purpose but he did and wouldn't answer my calls to see what I was supposed to do while _he was gone. While he was gone I got in touch with my old best friend that he hates anf I hung out with her since I dont have any other friends and had nothing to do. At thid point I really thought we was over and I was in my own. (Side note: I never doubted him taking care of his baby.) He called me when I was with her and I told him what I was doing. He got mad and came to where I was and caused a scene.

The cops ended up getting called and he was mad. I stayed with my friend that night and had my parents come get me the next day. Ive been with them ever since. Its been like a month and me and my boyfriend have been talking, he says things are going to be different if i just come home. He even cried. And I don't know what to do. I love him and want my family but he is always so angry and I dont want to fight anymore. He is getting tired of me being here away from him, which I dont blame him but I have gotten comfortable here and this is where my family is.

Can someone please help me. I am completely lost on what to do here. Also if anything is confusing its probably because I left something out, feel free to ask anything to clarify.
