This has never happened to me but if the breakup was amicable, I would say 'hi' but not stop to chat.

If my current b/f asked who 'he' was, I would tell him. If he didn't then I wouldn't.

say hello and keep moving

If it was me Id just smile at her and say" There IS Heavan after Hell"!!!!!

Runnnnnnnnnnnnnnnnn!!!!!

OMG, there she is!!!!! Look!!!

You would too!! Just another reason to love you!!

U know me too well my dear!!

And then not well enough!!

Depends on the ex. Probably just hi and move on. If it was one of the screwy ex, just ignore him

I get along with my ex's, so I'd just say "hi. How's it going?", chat a bit and move on.

LOL sorry evil thoughts... but how about... "Oh hi..I went to the clinic and got checked and well umm ..you should probably go in too. Have a nice dinner"

Probably make a serious double take since my Ex is passed away. lol One of the few benfits of being widowed.

While the "clinic" remark made me laugh if your Ex was a loser I think the best thing is to just do your best to rise above gracefully and go on and have the best possible revenge a pleasant date and hopefully great relationwhip.

My experience is Ex's tend to make even the best folks uncomfortable so if at all possible that is something I would avoid acknowledgeing about them if at all possible. If not be as breif and distant as possible. Even if I had to leave I would to avoid a confrontation. Nobody wins in those situations.
