In-laws from hell? Ignoring my husband because he won’t divorce.

Hello,

So I’m living a nightmare from hell. Me and my husbands family do not get along. His mom is very passive about his siblings and their behavior. Basically we live together and none of the grown children all over the ages of (15) some are older than me clean. Basically only me and their mom used to clean and sometimes only me. I got fed up and stood up for myself and in return they all started acting petty. Especially the mom. She doesn’t like when people tell her kids about their behavior (story is much longer and more events happened. The mom basically acts really petty to me even thought I’m pregnant) Basically my husband knows the full story and defended me over his family because he thought I was right and their treatment of me wasn’t good. Now that his family decided they don’t like me and want me out of the picture, they are ignoring him hardcore in the house. Basically forcing him to choose a side. The mom basically wants him to divorce me and abandon me, unborn child and our 2yr old son. We are moving in a few months but idk if we’ll last that long because their silent treatment is effecting him. He is slowly starting to resent me for the problem even though majority of it was their fault. He knows that but i don’t think he has a way to channel his anger. Someone please help. I feel like I’m in prison. It seems his family being happy with him is bothering him more than their injustices towards his pregnant wife. By the way the house we live in is actually ours, they moved with us because they depend on my husband financially.
