<human>: So I've had feelings for this one girl for over three or four months now. I'm older (17) by a year and she's in the grade below me. She's in one of my classes, and we talk on and off. We had some close interaction for about two months due to the fact that I was her partner for something, but now we've finished and we went back to how it used to be: talking occasionally. During those two months though we had a lot of fun: flirted, laughed, and enjoyed each others company. Anyway, recently I've been complementing her anonymously, and she has liked them a lot. She wants to know who it is, and I told her I would tell her in time. In the compliments I made it very clear how I feel about her, and I have stated the reason I kept it anonymous so far is because I wouldn't want to make things awkward. She replied she would wait until I revealed myself. So reddit, idk what to do. If I don't tell her she might just lose interest in the whole thing, and it could just blow over. Or if I tell her, she may be interested, but there's the off chance that it doesn't work and I'm stuck in a class for the rest of the year with her (might be slightly awkward.) Should I take the chance now? or wait it out? Also any advice on how to approach her? (This is the first time I'm actually telling a girl how I feel.)

Could you distill the essence of the text into 1-3 sentences?
