IMHO, one of the differences I have seen in the WW and the WAW, is a WW usually has a hidden agenda. Maybe it isn't completely hidden in some cases, but what I mean is that she either has another man waiting in the wings or she wants to live the singles lifestyle and powl. The WW is full of anger and disrespect toward the H. She is usually a manipulator and controller. Her selfishness separates her from what I see as the WAW who leaves for other reasons.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
