it's always best coming from your partner especially if it was an on going situation (judging from the OP it was more than once or twice). Seems like maybe he heard and was taken back and that probably upset him more. If he knew before he heard it on the street, he'd be better prepared when the streets mentioned it lol...you don't ever want to look like a fool. I guess his pride is a little hurt but if he truly loves her and if he likes old dude, then he needs to work through his issue and get back to being happy with his fiance and his new friend.
