Yes, sophiesmom, I read an article that talked about that. I did not post it for him though because I think it might confuse him and I am not sure that is what he is dealing with in this situation. Yes, some women would want their SO or husband to seek out this stranger and tell him to get out of dodge because he is messing with the wrong man's wife.
