My ex and i do a lot of flirting over msn (he has it at work) and we do meet up for coffee from time to time-only because he works very nearby to me. We are both happily married with children, and both know that we would NEVER EVER cheat and dont even want to-its not even an issue. We do reminisce and flirt a lot-well actually he does just for a laugh. My dh and his dw do not know of our undercover friendship! Oh i am friends with his wife so we do all see each other from time to time-she knows we used to go out but my dh has no idea because when i met him he said he doesnt want to know about my past! The question is, am i comitting some form of adultery?!! Should i feel guilty?
