I need help

19 and in a almost 2 year relationship, got pregnant while I had an apartment with family member then moved in with boyfriend and his parents, at 8 months he cheated: I went to a family members house for a breather and when I came back he had roses a nice note and things on the bed, I decided to take a shower with him and saw that he had scratches on his back. I realized he had cheated that night and then decided to get roses and all that lovey dovey shit the next morning. Denied denied denied until recently when he admitted to it. I told everyone in fam about him cheating while I was pregnant recently which was stupid I should’ve just gotten help the day I realized it happened. I don’t have anywhere to go LITERALLY. Very difficult relationship with family from both sides and I’ve tried moving even temporarily with them but they said I asked for it (him cheating) and that i put myself in this position. They keep asking why I’m still at his house and why I haven’t left but no matter how I re word it for them they don’t understand that I’m living in a manipulative prison and their solution is for me to tough it out. I would be able to if I knew I absolutely didn’t love him. I love him for our daughter but every time I look at him I get so angry that he thought I was stupid enough not to catch on to things. I live under his moms roof but i don’t want to leave the baby for her to baby sit because she’s the type of person to hand my baby off to everyone (also people I don’t know). I’m really really really lost. I feel bullied and unloved. I have a 2 month old. What should I try or do? I’ve tried making it work with boyfriend but im depressed over the fact that he cheated when I was 8 months and ironically now I’m remembering instances that I didn’t catch before where he was checking out other women and also I’m realizing a lot of times where he was up to suspicious things. I don’t know why I stay for the bare minimum. I’m emotionally exhausted I just want to feel okay. I tried talking to him about starting fresh and moving together and he said he was ready to be faithful and continue a family but that very next day I found dating app history on his phone from the beginning of February and it made me so mad because I was over here thinking we were getting somewhere. I had my kid in December. I am a wonderful caring and obviously forgiving person. I’m just not enough for him and i have no where to go so I can’t get up and leave just like I want to so bad. I need advice please help
