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

Alright, so I'm a junior in HS, going on to a senior, and this girl just transferred to my school quite some time ago (3-4 months ago). And we have only 1 class together, but I see her in between classes sometimes (and her locker's next to mine).

I never thought I would develop a friendship with this girl, much less, 'feelings' for her. And it's not 'feelings' as in, "hey, this girl's attractive", it's more like of how she treats herself and how she makes me laugh and how I make her laugh and that type of crap. I thought I was WAY too naive for this, so I just didn't bother, until a few weeks ago, when I realized how I felt about her. 

Recently, however, she's been getting more distant by the day and I have no idea what I've done. I haven't said anything to her about my feelings, nor have I made any indication towards her about my feelings, but maybe she's picked up on it somehow anyways? I don't know. 

AND because she's randomly stopped talking to me, I've been meaning to go up to her and ask her what's up and why's she doing all this crap. If it REALLY came down to it, I'd tell her that I love making her smile and laugh everyday, and that she meant the world to me. Thing is, I also trust her to tell me if I fuck up somewhere, or if I did something wrong, so I'd also tell her that if I did do something wrong, I'd put my trust in her to be brutally honest and tell me what I've done to upset her.

Am I going in the right direction with this? Also, I know about all the crap with, "oh, if she doesn't want to be friends with you, then move on". But, I WANT to be friends with her, and I WANT to know what's wrong. And I've NEVER said anything that indicated romantic feelings towards her whatsoever. Would anything change if I DID tell her about these feelings? Would it still be better for me to move on?
<bot>: Made a new friend, ended up liking her. Became good friends. She's stopped talking to me. Didn't say anything about how I felt. What to do?
