Advice pleasing don’t judge

I’m currently 8 weeks pregnant w my 2nd child . My boyfriend and I didn’t want another baby until our son is 3 he’s currently 1 almost 2 . When I found out I asked him if he wanted to keep the baby and he said whatever decision I made he would respect it but he would love it if I kept the baby . Of course I kept the baby I can’t have an abortion I just don’t have the courage to do such thing . Our relationship was going great we were fine we didn’t fight much if we did it was over little things nothing big . Well things started to change once we found out I was pregnant. Or maybe I was getting paranoid but we became distant . I started having some bleeding and went to the emergency room and I have a hematoma. I’ve been down lately not depressed but just very tired lately I sleep more than usual I’m in bed all the time . All he does is play video games . I didn’t think much of it until he started ti act different. He didn’t want to have sex w me anymore and we barely even spent time together. We just got in a huge fight and it lead to him being very mad at me for 2 days he said he needed space . We finally stopped fighting and when I thought we were fine again I went through his phone at night and looked at the messages between him and his good friend . He told him he was only w me bc of our son and that he was very unhappy. He said he wasn’t in love w me and that he doesn’t plan on marrying me but if I was to find out I would leave him . Which hurt bc he always talked about marriage w me . He was sleep so I packed all his bags and broke up w him through text and left to work . He woke up confused I confronted him about it and he said he didn’t mean any of it he was just very mad and he needed to let his anger out and he said things he didn’t mean he apologized and assured me it was not true . Idk what to do we are expecting a kid together and I’m very hurt maybe I’m very stupid for even giving him the benefit of the doubt. But prior to this we were fine he showed me love . Idk what to do I tried to move past it but it’s in my mind all the time now and I can’t forget it
