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

Idk. I tried adding her on facebook twice. The first time being back in December and that response was left for a week or so before I took it off, then the next time in February for like 5 minutes before I took it off. She's not shy, either. Am I overthinking this? She has over 500 friends and she doesn't post alot.

I'm in highschool. I'm a senior and she's a junior (18, 17). She doesn't know me one bit, aside from the fact that we have some mutual friends, and that she knows i'm in band and guitar, and that she is in choir (i've seen her perform).

So I said that I've seen her around alot, and then later on I asked if she'd like to do something sometime. This was during a passing period, I kinda chickened out the first time I tried and she might've noticed, but this time I did it. She said she has a boyfriend I said ahh bummer alright. That was basically it. I haven't talked with her for about 2 months, and I feel like I should since I don't think she has a boyfriend anymore and that I still think about her everyday. I've seen her walking while hanging with my friends, and the guy she was talking to got called over by my friends and she looked at me and walked on. 

I'm a bit worried to find she thinks i'm a stalker/desperate/creep/creepass/weirdo/asshole/player. But at the same time it's killing me to find out because I have 3 months (or 2 months?) left of school. Maybe I should just wait and she'll come to me?
<bot>: I asked her out, and she said she has a boyfriend. I'm worried she will think i'm desperate and it's been about 2 months since I talked with her last.
