Need some advice

Okay.. so I’ll start off with I’m 22 and 31weeks 3days pregnant , and I have lived with my boyfriend and his family since we started dating (almost for a year now).. I have recently decided to move out back to my moms.. for financial and mental reasons..

but when I told my boyfriend I was planning on moving out my anxiety was so bad with the thought of him leaving me, or leaving me and our daughter. But he kept telling me we can still date and not live together.. and then I told him I was worried about him leaving me for someone else and he said stop worrying.. so my anxiety went away..

now that I’m actually moving out next week my anxiety is back, and it’s back full bore..and I know if I talk to him about it.. he’s just going to get mad, or frustrated..

Like I am just worried as soon as I move out , he’s gonna be either talking to other girls (not necessarily cheating because I don’t think he would do that) .. then he’s gonna find someone he likes better than me and leave me for her.

I’m also worried about barley talking to him, he gets mad now when I text him threw the day (which yes he doesn’t want to be bothered at work which I understand) but like I’m scared we are barley going to talk and we are just going to drift away from eachother.

Like we have been threw hell & back it feels and I don’t want to loose him. It’s one of my biggest fears and I don’t really know how to stop it from happening.

I will also add.. he won’t move out of his moms house.. so getting a place together is out of the question..

but there is constantly fighting at his house, yelling and screaming and stuff slamming..

very vulgar language used ALL the time, I just can’t have my daughter around that.
