He needs to be taught how to treat his wife. My son is an abusive 25 year old. He lives with his GF who is 37. When he opens his mouth to her and calls her names, she kicks him out. Last time he had to read a book on abusive behavior and go to a therapist for anger management before she let him come back. I don't know how many times she will kick him out before she does it for good. But she is making a difference with him.
