Jpeg and Scidad, the WW doesn't have to be in an affair to qualify her as wayward. It's her hard, cold heart, and the selfish attitude she has. It's her meanness and bad treatment to her H. It is the complete change you see in this woman you M and now don't know who she is. Even her character/integrity can change! Three main areas that I have seen in all WW are disrespect, resentment and rebellion. The root stems from these areas and then the selfishness takes over. I do believe that b/c of the rebellion that finally kicks in, that she will eventually get involved with someone.
Some are worse or to a greater degree than others, but I have seen these common things in all the stories, and the ones I have known.....and in myself.
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!
