dear internet, so I have this crush on this amazing gal you see, but before asking my question, have to give a bit of back story.

We went on a few dates and she decided that maybe I was a bit too young for her and maybe she wanted someone more mature for a more long term relationship kind of thing. but she didn't want to rule me out completely because we have great chemistry and loads in common. After a week of me needing some space to adjust to this change of relationship status (as I am sure some of you know, being just friends with a girl you really really like is a challenge) she tells me she'd be disappointed if I didn't come to her birthday party thing with 40 buddies of hers (including an ex and a few guys she flirts with). I agreed knowing it would be uncomfortable and unpleasant for me, but celebrating someone you care for is what a good friend would do - short term discomfort is worth it for long term friendship, right? An excruciating hour and half into the get together I mention that I have to leave to catch a movie with friends (which was true). When I hug her goodbye she tells me she's angry, I ask why, she says we'll talk about it later and I leave. I sent her an e-mail today to see if all was well and I get a malicious e-mail back stating how raving mad she still is and how she does not want me to sit beside her in class etc. I am left slightly confused as I don't really see what I did that was so wrong.

So, my question is: should I believe her, am I really a selfish dick?
