I can under stand her anger but she needs to contact a divorce lawyer. Assaulting her husband doesn't help. They'll probably try to paint her as a violent wacko.

Is the husband hot? Or is it that he has hot money? Nothing like the stress of a husband catting around to quickly wilt even a pretty wife. The best revenge may well be to let those two have each other as they probably richly deserve each other and to retire living high on the hog herself if possible.
