<human>: Can you succinctly summarize the text in 1-3 sentences?

Met her a few years ago. We hit it off. Stopped seeing her. Last year, we were both in the same english class. She acted really into me. When I said I liked 'x' TV show, she would make sure to say she likes the same exact shows. She would ask me to sit next to her in class. I moved away, not sure why. But we would just stare at each other the entire class laughing/smiling with each other. Around prom, I didn't ask her. She got mad at me for that reason I think, idk. Year ended, and we were still cool. 

Fast forward to this year: She started the year by trying to talk to me/smiling at me and shit, but somehow moved to like..hate me. Frankly, I have absolutely NO idea why. I asked her if she wanted to sign my yearbook and she signed it, then later said to me, "Your yearbook was the only one I felt forced to sign because I got caught up in the moment." I also get the occasional death glare. Everytime I see her, she makes a big deal of ignoring/rejecting me.. 

I like her more than any other girl I've met thus far..She's smart, pretty, funny, athletic..Can't think of something I dislike about her. I want to talk to her, but I never asked her for her number last year. Now, given the circumstances, I doubt she'd give it to me AND we see each other a bunch but like ignore each other. Wouldn't it seem creepy if i just suddenly show up and ask to talk to her/ask for her number?
<bot>: Girl liked me, now she somehow hates me. Not sure why. Think it might seem creepy if I ask to talk to her.
