Criminal Conversation

First let me say that I am not proud of what I have done but this is the situation I an in.

I’ve had an affair for about a year with a friends wife. She and I were both in unhappy marrages but her’s a bit more severe. He has physically beat her, tried to kill himself twice when she’s tried to leave him before I knew her, threated that if she ever leaves he he would tell the kids everything and then kill himself, He has had an affair of his own, Has searched out swinger couples and invited them into there bed. (she refused), had sex with here best friend, and now hes moved out to TENN and is filing against me for taking his wife away. Any advise would help.
