Well, I think they do wonder. When I started to date someone, my H was very concerned about what I was doing. He called me while I was having dinner with a "friend" because he became suspicious. When he confirmed I was on a date he started to cry and said he couldn't stand the thought of me with someone else. And he called in the first place because he was missing me. Of course I wanted to smack him upside the head and say, what the heck do you think I've been feeling while you are running around with OW. I think he was more worried that I would become emotionally attached to someone rather than the physical aspect, although he asked if I had slept with him, because he wasn't emotionally attached to OW. That was no because I didn't really like the guy that much and still wanted to be with my H. I think they really do care and are very sorry and they are trying to find anything to make those bad feelings go away. But right now they don't want to be back with us permanently for fear things will be the same way they were before.
