I don't really know what to do.

So I've had a bit of a crush on this girl for a little while.

I talk to her a good bit. I really doubt she likes me, but there's always a tiny voice in the back of my head replaying every single tiny insignificant moment that might indicate her liking me. She's come up to me in science a few times and asked the stupidest question I've ever heard that she could've asked her friend next to her, the teacher, or just read the damn instructions. She came up to me in the hall earlier this week and talked to me for a bit, and we talk a bit in some other classes. But that's pretty much it. But the thing is that her texts are SUPER dry. Holy shit I have never met someone who texts that dryly.

Also, she's popular. Not super popular, but still kind of popular. I'm not at all. I'm not a loser, but I'm definitely not that. Because of that, I know I'm probably being paranoid, but I feel like she could be teasing me or leading me on. I know that probably feels insane but I don't know. Anyway, what do you think I should do? Keep talking to her and building a relationship, just ask her out, stop talking to her, do you think she might like me? I have no idea and I feel insane.
