She says she did not have an affair and I do believe her.
So, we don't get very far into slight touching, and she begins crying and asked to stop.
To me she seemed like a woman who has been sexually abused or raped. Neither of those have happened to her though.
Sounds more like a woman who had an affair and is full if guilt for it. Maybe the reason she came back is because the other man broke it off. If she broke it off, she would probably have another man ready to go.
