Sad and confused about his behavior

I'm the wife of a truck driver and it's very difficult. I find it hard to believe all his habits prior to me have "changed"...picking up prostitutes hanging out at bars and strip clubs, picking up female hitchhikers. Stop seeing the woman he's met on his trips and his behavior when something doesn't make sense he becomes angry and violent.

None of this makes sense or does it....I know I don't deserve this yet he can never lovingly put my mind to rest.
