I'd never heard the term "emotional affair" before I joined MN. These "affairs" seem to be seen here as actual cheating. I can see that they might be cause for concern, and make the partner who isn't having the "affair" feel very uneasy, but I don't see how they qualify as cheating. Surely, the fact that nothing physical happens is the very definition of not cheating. I am not having an "emotional affair" with anyone, and I'm not sure I'd want one, but if it did happen I don't think I'd feel that I was cheating.
