Starsky, thank you for responding. H and I are both in IC. Before the A was exposed we had a few sessions of MC, but at that time they did not help much. I think that was partly because H didn't really like the C we used and was not sure about saving our M. I probably need to broach this with him again and try and find a different C.
I did expect that he would have a period of withdrawal. It seemed to me like he may have started that prior to officially telling me he'd ended the relationship. I'm not sure of that is true though.
I do not have any other form of Intel except snooping or following which I'm not sure I like. Do you have any suggestions for other ways to verify? We are relocating soon which will take away his ability to see OW easily. That doesn't ensure that they will not talk though. Trusting is also complicated by the fact that H frequently travels. He's been sending me his schedule and calling to check in multiple times a day when gone. That does help ease my mind. FWIW, he didn't hide well that his life was in crisis which makes me feel better about his ability to continue hiding things. That may just be naive on my part...
