Gypsy, I don't know if its because a guy feels more strongly about another person, but more of a newfound attraction, an 'addiction' if you will to the attention. In one of the books I read (Not Just Friends, I think), it mentions how a WAS has to build walls. They have to build a wall in between them and their spouse in order to let the new person in.

That's interesting Lwb! Now I want to pick up that book and I have so many others already! But my H tends to either be very distant and angry and that started I think when he started his EA and of course worsened when the PA started in Dec. He won't touch or even hug me even the day before my brother had his brain surgery!!! Karen
