I had the misfortune of finding a picture of my H and OW and a nasty card to him from her one time in the early days when I was "snooping" (while I was still in the house). I have to admit she is kind of cute in a way. She's 32, H is 36 and I'm 39. Younger woman thing kind of gives me a little complex. What I meant though, was that it doesn't matter how cute or ugly OW is, H's are attracted because of their "like" energies.
It sounds like your H was looking for an "excuse" to call. That's good! I think you're doing the right thing by dropping the ball and not calling back.
Like I said in my thread, H didn't see me, but I just wanted to call because I missed him and wouldn't have had a good excuse so I'm glad I didn't give in and do it.
