I don't care for my husband's family and I live with them
Why does your husband allow you to live with his family?
He wants to avoid money problems and his family doesn't make us pay bills.
You don't have to like your husband's family. But you're stuck with them, so you should try to be civil at least especially if they allow you to live there rent free.
How do I get out of this mess
If you really don't want to live with them that badly, then you should move out and pay your own bills.
