I love your proposed conversation between FB and her H. I had a similar conversation with my H when we first got back together. Even today, I will ask him if he talked to the OW and he will say just business and that's it. Unfortuately, they work together but not in the same building. They work in the medical field. He said she will try and start a conversation via IM and he remains business with her and ignores everything else. At least this is what he has told me. And I believe him until he his behavior tells me something else. In the past I could always tell if he was talking too much to another female because he would come home and ignore me. Like he was feeling guilty about it. But I have not experience at all.
