I lived that way for 31 years and then found the book which saved my life: The Verballly Abusive Relationship by Patricia Evans. He isn't going to change, and every day he is teaching your children disrespect and anger. You must save them and yourself. THere are so many resources out there. Call an abuse hotline (google domestic violence), call a shelter, hospital; keep on writing here. Your children are counting on you to get them out of this violent situation.
