My husband and I have had a very rocky marraige to say the least. Weve only been married for 2 years a well. We have a 19 week old son together and since hes been born it's gotten so bad. He tends to get violent and I say things out of built up anger, the only times things were looking good was when I was pregnant and the beginning of our marriage but weve always tried to work on things. 3 weeks after my son was born my husband got arrested for domestic violence. He hit me while I had my son in my arms twice and choked me out. I flipped because I was holding my boy and called 911 cops came and long story short he got arrested. Since that night I've held a lot of resentment one because I was holding our son and two because I still had stitches from my c section and he was okay with risking me popping a stitch or worse potentially hurting my son. Since that day we havent been the same hes constantly making accusations of me cheating and just starting stuff. Hes done a lot of horrible things to me especially before I had our son. Hes choked me to the point of passing out repetivly and forced sex on me. Hes hit me and told me numerous times hes going to kill me. A week ago I told him I wasnt happy and didnt want to be with him anymore, cue violence and making me feel guilty and end result agreeing to work on things. Well tonight we got into another fight and I said "it's over" and he stormed out of the house and I have no idea where he is. I feel so many things right now. I'm sad, relieved, and at the same time want to take it back. Someone please tell me it's going to be okay. Theres also a possibility I'm pregnant again and I'm so scared. Idk what to do
