I was drawn to your thread because it struck me as similar to mine -- H. and I have many good things going for us and spend a lot of time together enjoying each others company but he's still in contact with OW. I didn't have hard proof other than his behavior but I confronted him about it this weekend. Looks like it's going to take a LONG time to get back to how good things were before
Anyway, you said something interesting in your post that W. "couldn't trust your reaction" and therefore didn't tell you something. That's a nice direct statement -- have you mulled over what exactly she might mean by that in terms of what your reactions are that she has trouble with? Do you think she would ever tell you that she misses him, etc?
FWIW, my H. made it very clear this weekend that he does not consider OW "the issue" and perhaps he's right -- next goal for me it to figure out what he DOES think the issues are.
Check out my thread if you've got time and I'll be sending you the best of luck (and perhaps the occasional comment) on your sitch.
