Does this girl like me?

We're in the 11th grade and she is probably one of the most beautiful and popular girl in the school who could have any guy she wants. I'm just a loner/loser who doesn't talk to people very often and She treats me like a gay bestfriend even though everybody knows I'm not gay. I kind of like her, what should I do?

I asked this question earlier but only received 3-word responses that aren't helpful.
