divorce?

I'm stuck I love my husband so much but he goes to far sometimes. Like he's adopting my daughter but every time we get into it he says he's taking his daughter (my step daughter) and leaving then we argue and he never leaves. But literall he blames everything on me he's never in the wrong or doesn't know when to admit it.. and he acts like smacking my phone out of my hand is ok.. idk what to do I quit my job to take care of our daughters and I'm 24 weeks pregnant so paying all these bills he built up alone is gonna be impossible 😭
