Advice please

Be prepared for a long story. I need advice. 
So my husband and I ran into financial trouble and made the decision to
Move in with my parents. Last night, my husband and dad got into a very heated argument. I'm not siding with my husband on this because he was drunk and cursing and said some things he'll never be able to take back     . So my parents have said they are done with him and that he can no longer live with us but that I am still welcome to stay. I want to stay because I think my husband and I need time apart. My parents are trying to take control of the situation and arrange for a divorce lawyer, and make it to where my husband would have to prove that he is the father of my child. They don't want him to have visitation rights. I've tried to tell
My parents that I have a say in what rights he has as the father and that if he wanted to fight me on it; then we would go from there once our son is born. I'm 35 weeks and I'm very stressed out and not sure what to do. Both my husband and my parents think they're in the right about what happened last night. I'm stuck in the middle. He is going to stay with his parents until he's done with this semester  But I don't want to go live with his family. They don't have the best living environment for a baby, and as far as I know, his dad does drugs while away from their home. 
What do I do?
