Let me tell you guys a story;

So I have a 2year old daughter and before I was pregnant with her I started working at a restaurant where I met this guy that I saw and i instantly fell in love with as time went by we flirted and it seemed like we were feeling each other so I got the courage to tell him I liked him and that I’d like to be more than friends and he basically told me “no thanks, you got the wrong idea” so I was hurt and embarrassed cause he told his friends at work and I just couldn’t be there so I quit.. (for a few weeks then I went back) after I went back I found out I was pregnant with my daughter (I was on and off with her dad) and the guy and I still talked but nothing serious I worked there all through my pregnancy and left on maternity leave, i took a year off. When my daughter was 3mo the guy messaged me asking how mom life was etc.. i did small talk but i eventually stopped replying because my daughters dad knew about how I felt about him and he would hit me an verbally abuse me for it so I didn’t reply to him so I could make it work with her dad. When she was around 5 months we broke up and we coincidentally started messaging and talking to each other again and although my daughters dad and I weren’t together he would still hurt me over it so once the guy and i became official I moved out and moved in with my cousins wife and her daughters, & her sister lived there too.. her sister hated me growing up so I tried to make conversation and be nice and be friends cause we were going to live together, well she started getting too close with me, we started to have sleepovers in my room etc, etc, and one night she got close to me and started touching me and wanting to finger me and although I didn’t want it I couldn’t stop it (in the past growing up I was touched and abused by family members and family friends so I felt trauma and scared and i froze and it was a given to not tell anyone about it) so it happened and i was confused and didn’t know what to do or say, she touched me over my underwear and nothing else so I told my bf and he was upset over it. Beginning to date he didn’t know about my past with the men who’d touch me, it wasn’t something that was easy for me to talk about so he just thought I messed with this girl. I couldn’t move out or people would ask questions I couldn’t distance myself cause she was living there and I couldn’t just stop being friends cause we got close and people would ask questions. It happened about 2/3 times more I think, and she wanted it to happen more than that but I didnt let it, and this guy he was understanding and loved me and was amazing the whole time, he said he wanted everything with me he proposed and we moved in together after livin with my cousins wife for 8mo, we lived in the apt together for 3 when he moved out. Because I was distant and because of the girl. He told his parent literally everything and he took them to the apt to help him move everything out. I didn’t say anything I couldn’t.. (we had to end our lease and pay whatever fees, i had to pay 1200 and i have to find a place to put out furniture and things that dont fit with my mom where I’m staying) so a few days later we talked he said he was too hurt over the girl and that’s when I told him about my past and how I didn’t want it that was in November and since we have been talking and trying to work it all out, I love him so much and after everything I’ve been through to be with him I can’t walk away, he says the same but it’s hard for him to trust me he says. His mom expects us to be over and broken up and we’re taking it steady.. thing is one of those times we got together to talk we didn’t do much talking & we just found out I’m pregnant. His mom said she didn’t know what to think & I asked where does that put us & he said we’re still trying..
what do I do.
