Ok, I'm 24. On friday I went to a bonfire that one of my friends from high school, a girl named Lauren, invited me to. In high school, we had a brief history, I made out with her once and basically could have fucked her, until I started going out with my current girlfriend. My girlfriend has never liked me talking or hanging out with Lauren, so they have a kind of tense relationship.

Anyway, the week before the bonfire Lauren kept texting me saying how excited she was. She told me my girlfriend was obviously welcome to come. So my girlfriend and I went to the bonfire, had a great time, I basically made my rounds with everyone, drank a few beers and played beer pong. The whole night though, Lauren hardly said a word to me, it almost felt like she was avoiding me. She would even come up to groups I was in a conversaton with, join the conversation, and basically talk to everyone but me.

I guess my question is, why would she invite me, act excited to see me and shit, and then basically avoid me? I could be over analyzing this but it just seems weird.
