<human>: Could you distill the essence of the text into 1-3 sentences?

I am a 15 y/o guy in my sophomore year of high school. There is this girl in my grade, and a few of my classes, that I really really really like. Me and her have been going to school together for about 2 and a half years, but I haven't really gotten to know her well until about a few months ago. Her and I have a lot (and I mean A LOT) in common. We're both redditors, we both like similar music, play video games, the whole shebang. Also, she is my next-door-neighbor, so that's a bonus. Some background: I recently got out of a 4 month relationship (my first real one) with a girl that I didn't really like that much. I was glad to get out of there, mostly because I really was starting to like this other girl (the neighbor one). Her and I have become very close in the past month or so, and we see each other everyday in school and most days after school. It's nice and all, I get to spend time with her, but I want to, you know, take it up a notch. I just really am starting to feel like she doesn't like me that way, at all. So, would it be weird if I told her how I feel and she didn't feel the same way? I don't want to lose our friendship, but I really want to be with her.
<bot>: Should I tell one of my best friends that I really like her and risk losing our friendship, or should I just stay friends and have to suffer through seeing her everyday and knowing I can't be with her?
