This is based on my own experience with my W, but I think that once a woman is emotionally connected to someone else she can no longer see the potential for a reconnection with her husband. Typically, woman check out emotionally before physically. Also, I think that in the mind of the adulterer, an EA signals far greater problems in the marriage than just a PA. All of this is based on the assumption that you can have a PA w/out an EA. Of course the combination of the 2 is probably the most deadly. Again, I don't mean to generalize, but this is based on what I've seen w/my W.
