Maybe Jenny Sanford is a total b-i-itch and he was so sick of putting up with her crap to the point that he didn't care anymore. Maybe even, she was the kind of "loving wife" that continually accuses her husband of cheating so he decided one day, why the hell not? She already thinks I am, I might as well have something to feel guilty about?Whiney and pathetic excuses.
If you're unhappy in your marriage, get counseling or get a divorce.
Your "solution" is the cowardly scumbag route.
