Any problems with the OW? Do you have kids at home yet? The reason I ask is that you can only put forth so much effort and time to "Cure" a ND woman. If you have genuinely done every last thing possible to "Cure" your wife, then maybe it is time to move on. Your wife sees things like my wifes sees them. They have very BIZARRE ideas for marriage. Who ever told these ladies that it is ok to not be sexual or to want intimacy. This is truly bizarre behavior, especially in a world where sex is everywhere.
