Don't know what to do 😢

My SO had been friends for years before started dating and we talked about having a baby eventually. Well we go to party few drinks and knowing I'm wasted he magically forgot to wear a condom. I figured he was drunk too so I never got mad and figured it was both our fault that I got pregnant so soon.

Well the other day he had a few beers (I encourage it... He hasn't been sleeping well taking care of me while I had the flu)... After he's had a few he's looking for attention and I Crack a joke about how this how we gotten into this mess with a baby on the way.

He said on I was not drunk, I just wasn't going to let you get away from me.

I froze... He knows how much I've regretted the timing of this baby. I hadn't been living with him and his kids long enough to realize that their life style no way matches mine, it's been an on going fight trying to get them to clean up after themselves, roaches everywhere, disrespectful etc. I've gotten to a point where I'm ready to leave and then I feel guilty cause it's his baby too and their little brother... So I start and try to make it work.

Maybe it's hormones but since finding out that it wasn't an accident I'm livid I can't stand being around any of them. I've taken to hiding in the room lying and saying that I have a headache ... I told my sister and she wants me leave... I don't know what to do in do confused and I feel betrayed.

I'm tired of the mess and the fighting and just don't want to rely on my family for help but don't want to be around him either.... Any advice?

Before I left the house and after photos. Tell me if I'm wrong to get pissed... I was gone two days
