I'm sorry for the long rant :(

Please no judgement because this is all still really new to me and its fresh and quite honestly I'm hurting badly. I'm 26 weeks pregnant. Today what I thought was the love of my life told me he slept with someone else a couple months ago. It was while I was pregnant. Completely heartbroken And shocked I freaked out, broke a couple things, he kept trying to restrain me and keep me from leaving my house and I ended up catching him in the face a couple times. He begged and pleaded for me to forgive him and I repeatedly said no I couldn't and that I wouldn't he cried and cried and said he fucked up and that he was so sorry and I'm sure you get the jist of it. Still in shock I sat there in silence for a little bit but continued to tell him no and that I would like to leave now. He blocked the door to our bedroom and refused to let me leave until I said it wasn't completely over. I still refused. He then kept making comments threatening his life and I just continued to tell him that if he really cared he wouldn't have done it in the first place and he would just cry harder. After at least an hour of that I finally left my house and got to speak with a friend although I didn't have a lot to say... I spent a couple hours to myself just driving around crying and then I parked at a church by my house and ended up accepting a call. He came there and got in my car with me and I just cried and continued to tell him how shitty I think he is. We were there for a while. I then told home wanted to go home and just be in my bed and he wanted to come with me but I told him I know I should say no and that I know I deserve a lot better than this. He asked if I was going to cry more and I said probably and he wanted to come still he said he would sleep on the floor. This brings us to now as I lay on my bed uncontrollably crying as he lays on the floor in silence :( I know, it's bad, I should kick him to the curb; easier said than done... I haven't given him any hope that there's a chance and I haven't let him touch me. I'm just so hurt that he'd do this to me and our unborn son. I wasn't expecting it.
