You know what makes a man confident? A women that sexually desires him! Whan a man KNOWs that is wife does not desire him, his confidence will take a MAJOR backslide. You have to remember that for many men, the point of thier lives is to be needed by their wives, but when they have a wife that does not need/desire them, their world falls apart.

Someting else that happens is that men who know they are not desired end up AVOIDING conflict, since they feel they must appeal even more to their wives. They try to avoid the boat rocking, when they should be boat rocking.
