How to Survive a Broken Marriage

Long story short I am in an abusive relationship with a mean alcoholic, I am 32 weeks pregnant and he is the only income since I’ve become pregnant. I never thought I would be in this position, but if I leave I’ll have to move in with my family again and I don’t want to put that burden on them. Anyone else been through a similar situation? How do I make it through this alive? I’m all alone and scared.
