<human>: Give me the gist of the text in a nutshell

I'd like to preface this by saying I am clueless about ladies, especially when I find them pretty, so I need some help/advice. 

I sit next to this girl in my 8am history class, and I have a bit of a crush, but I don't think she feels the same way. We talk a little during class, and we always talk before class starts and after class ends for a little bit. I asked for her number and she gave it to me (though she seemed to be somewhat reluctant). It's been a few weeks and nothing really changed, except we text (only when I initiate, she has only started a conversation once or twice). I asked if she'd be interested in hanging out sometime and she said yeah (not too enthusiastically, though shamefully it was over text so I can't really be sure), but she said she wasn't available that weekend, so I told her that was fine, just let me know whenever. She hasn't brought it up since and that was a couple weeks ago.

All in all, I'm pretty sure she's clearly not interested (and I'm pretty sure she's single because she talked about someone we walked by as looking "just like" her ex boyfriend), but I was wondering if there was any way for me to figure it out without just asking straight up, which I know would most likely be best, but you see I lack the testicular fortitude to do anything like that. Asking for her number was hard enough.

Now one of my friends, a guy who gets with many more women than I do, says she's just being a girl and you never know, but another friend, a girl, says it's pretty clear this girl isn't interested. What do I do?
<bot>: I like a girl, don't think she likes me but I'm not sure. Also, I have no balls.
