I don't get this. We have similar lifestyles but my ExW's OM is clearly an ego boost whereas I can't see that in your W's OM (if that's what he is).
I kinda get the impression your reading too much into him. Now, that doesn't mean it's not an inappropriate R she has with him that should stop but it doesn't have the hall marks IMO.
I think you may be looking in the wrong direction. Idk but it just doesn't pass the smell test. Know what I mean?
