I think you will find that all or most of the experienced vets on here will tell you NEVER move out. Don't leave the marital bed and don't move out of the house.

Review DB and DR paying close attention to the sections dealing with boundaries. It sounds to me like you may need to set some firm boundaries to protect yourself and your child.
