I don’t know if I did the right thing

My husband and I were estranged. I hadn’t heard or seen him in about 3-4 years we’ve been married for 5. On Thanksgiving he called me randomly and we decided to meet up and have dinner. He seemed so different and more uplifting and positive. Prior to his leaving he was just very distant and defensive and constantly told me how he felt he needed to leave to make more money and pretty much blamed me for his financial difficulties- but his difficulties stemmed from his past and I did everything I could to help him overcome it including helping him look for work. For about a month after our initial meeting on Thanksgiving I was happy to see him and be around him but the week of Christmas he started acting standoffish and weird. He was acting hostile towards cashiers as we Christmas shopped and even had an explosive moment over the phone with one his family members. I chalked it up to him being upset over family squabbles but the entire week he was just starting to distance himself. Finally on Christmas eve he was being really stand offish and really angry like my presence was bothering him. Truth be told it wasn’t until that moment that I realized how much I had in fact grown since he just walked out one day and never came back. We were staying in a hotel and I stood to myself and stood on the other queen bed just letting him have time to himself when I decided to try to make amends I asked him to move over and his response was “you can go lay on that side you don’t tell me what to do. I don’t need to move.” I honestly was floored because I said “babe move over so we can cuddle” and that was such a cold response. I went back to lay down on the other queen side bed bc who wants to share a bed with someone after that ? He responds to that with “ you can go back home for all of that”. So I got dressed and I grabbed my things to go home. He then gets dressed and demands I take him home. So I did. Worse hour and 45 minutes of my life: he proceeded to yell at me because I was crying and shouted at me and just said horrible things. He asked for my wedding ring and engagement ring back ( although I did give him my Christmas gifts back it didn’t feel right keeping them especially because I knew where it was going) the next day he proceeded to tell me I wasn’t worth anything and that he’ll never respect me because of the fact that I don’t earn over a certain amount of money and I can’t do anything for him. I stopped all communication except for this week when I found out I was pregnant. He gives me abusive vibes and I hate who I am when I’m around him. I literally remembered how much I hated being married to him. I told him I was pregnant and he automatically thought we were getting back together but after a few days my feelings came to the surface and I told him I didn’t want to be with him. I don’t know if I did the right thing. I haven’t heard from him since. I’m in the hospital and I’ve called him a few times and he’s not answering. I’m tired of this marriage and of him. Idk if it’s hormones but I can’t stand the thought of going through this pregnancy with him next to me. Did I overreact?
