Anyway, he needs to grow a pair and stand up for himself. That's all there is to it. If she won't go to counseling, then he needs to decide what he's going to put up with and what he's not going to put up with. There is really nothing else to do or tell him.
I also agree with the other poster who says you only have his side of the story. Remember, there are three sides to every story - his side - her side- and the truth (which is usually somewhere in the middle).
