Cheating wife crazy, anyone else....?

My cheating wife (every day, same dude for 2 months) and I are divorcing. Here is the thing, she has done every horrible thing to me that she could possibly do from an attorney standpoint. Some of the things she has had her do I cant believe!! I just laugh and think to myself...yip, keep it up, run that bill up, Im gonna be making a ton of money the rest of my life so its nothing to me. Now, heres the problem, I cant be mean to her, I just cant. She has beaten me requiring medical attention, and the police where called. I could not raise a hand to her. She has accused me of any and every financial atrocity known to her attorney. I just dont know why I cant be mean to her, she is even driving one of my company vehicles right now...I loaned it to her. I have not allowed my attorney to hurt her in any way, even at her urging.
