Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
I'm afraid the only way to deal with it is by leaving the abuser, because he isn't going to change. Things don't get better, they get worse, and it will eventually make you ill.
Take care
Artemis is right. The only way to "deal" with it is to walk away from it. You can't change it, you can't change him - you can only change yourself and your situation.
There really is no dealing with it, as the other posters said. It won't change. And if you have kids together, God help you, it still doesn't end when you leave.
