Wow - I'm having mixed feelings about this. I feel sad for you that you are dealing with such a negative effed up situation. I also have the "You gotta sleep in the bed you made" sort of feeling and I feel sad for the wife.
IIRC though, you knew he was married and your attitude about the whole situation was very different when it was all fun & games. Now that its real and "in your face" it sucks bigtime.

What do you do? I got no idea - Apparently you were "just having fun" - then tell him to go away, delete/block his #'s from your phones, apologize profusely to the wife & move to Budapest.

Are there kids involved? How long have you been seeing him? Does any of this matter, really? - I dunno - just trying to get a better overall picture of the situation.
