I'm officially a tramp. What do I do now? [View All]

Some of you may remember that guy I was telling you about--hadn't seen him in a while, but I found I still liked him. We've been emailing, nothing underhanded or flirty...I saw him again yesterday at a party for a mutual friend, everyone was drinking, long story short, he kissed me, his girlfriend saw, I feel like a tramp. I left, she left, he went after her.

Clearly I made a poor choice, and I have no plans to call him or anything. I feel very poorly for the girlfriend, who earlier in the evening told me how much she loved him...if that happened to me, I'd be devastated. He on the other hand, detailed the depths of his affection for me years ago and told me that I was beautiful and bla blah blah. I didn't tell him much, he was doing most of the talking. I should have walked away, clearly. I feel dreadfully immature and ridiculous to even have this story to tell. I imagine they will reconcile and he won't see me/talk to me again. However, if he contacts me, should I:
