Not sure why you feel filthy since you stopped everything including friendship & even told the girl & you didn't do anything more than hold hands & hug him as a friend. You are not responsible for his actions only yours & you did the right thing when you realized where he was coming from. Might have learned from these situations that comforting a married or engaged man with physical closeness only opens the door for things like this to happen. It would be good to remember this in the future & make your choices based on the wisdom you have gained from this. It's good that it wasn't anything more than that which the guy tried with you & that you kept your boundaries & made the fiancé aware. It's obviously her choice..will be interesting to see how long their marriage lasts before he's off looking for someone else to have an emotional closeness with outside his marriage this time.
