So I have a party coming up and this girl who I previously hooked up with is gonna be there. After we hooked up she started told some of her guy friends really personal stuff about me, who then proceeded to tell a bunch more people, and on the whole a fairly large group of people now know.

Obviously this has been very embarrassing for me. While it happened a while ago I haven't seen this girl since, and this party coming up will be the first time I see her, as well as some of the guys who she told this to. It's quite a small event - 30 ppl or so - so it might be hard to completely ignore her or these guys.

So I need some advice, how am I supposed to act here towards her? My feeling is to ignore that she even exists, but how should I act if I do end up having to acknowledge her?

Cheers
