As of right now I strongly believe it is an emotional affair and hopefully I have stepped in just in time before it become something more.
Only a DAM (and trust me, I NEVER use that term, b/c I generally don't like it) characterizes an emotional affair as "just" an EA. To a woman, it is FAR more serious for her go give her heart to another man in an ongoing, emotional relationship than to give in to him for a ONS or even a period sexual one.
If you don't believe me, just poll the women on the forum.
ONLY A DUMB-ASS MAN MINIMIZES THE THREAT OF AN EMOTIONAL AFFAIR!!!
