I need advice!

I’m 23, and I have a daughter and another one on the way, and my boyfriend isn’t ready to buy a house yet or to move out of his place, but I have already lived with them once and moved out a month before my daughter was born because his mom treated me like shit my whole pregnancy and was trying to force me to abort her.. and I couldn’t afford rent so I ended up moving out.. now my boyfriend is wanting me to move back in because he wants to be with his kids more (which I understand) and his mom is now okay with my daughter and this other baby.. but I’m scared

I currently live with my family, and my mom is VERY attached to my daughter which is getting alittle irratatinf she tries to force how I raise my daughter when I’m there.. so I told her I was thinking about moving back out to my boyfriends and now she’s guilt tripping me :(

But like my mom does help me out a lot when I’m at home so if I move out I won’t really have that much help.. which is worrying me too
