Should I give up on this girl?!?!?!?

[Micheal]

So there's this beautiful girl that I've liked for about 5 months now. I just don't know if she's interested in me. We don't go to the same schools and BARELY EVER see eachother. And I'm not even that close with her. I texted her a couple times like 2 weeks ago and she didn't reply. And I don't have the balls to text her again cause I have a feeling I might be annoying her. I really really like her and care about her, I just can't tell her. I REALLY need help! I know her instagram and Facebook and twitter, but I don't talk to her on those either. I really need to grow a pair rofl but please guys and girls I really need a way to get her attention. And also, recently I've been dreaming about her, and I can't get her off my mind. I really don't know what to do:\
And also, the first time I met her, it was me and a couple friends and I was sitting in the middle, then I heard her whisper to her friend( but she didn't do a good job of it ) "I like the one in the middle" I'm not sure whether she said this in a friendly way or if she said it in like a flirty way. Either way the whole time we were talking she would stare at me a lot and then after I saw her she stopped. We don't even talk anymore and she's really popular at her school ( I MEAN, REALLY ) and to me it doesn't make sense how she could like me out of everyone in HER school. So should I just give up?

If you are sure that she said to her friend "i like the one in middle"
then don't give up try to talk to her maybe she likes you.
