<human>: Summarize the given text in a few sentences.

There's this girl in my class at my university that I have a crush on. We both talk to each other in class and since the professor is pretty damn boring, we started to get to know each other by talking often. I want to ask her for her number, but I don't know if she has a boyfriend and just asking her if she has a boyfriend out of the blue is most likely going to come on as a tad bit weird. 

Also, I see her texting on the phone as well from time to time and sometimes she's smiling while she's texting. I just can't help shake the feeling that she does have a boyfriend and I don't want to feel like an idiot and ruin the possibility of even being friends by asking her when I still don't know her very well to ask questions this personal.
<bot>: I have a crush on this girl in my class but I have no idea how to confront her about it and possibly ask her out as naturally as possible. Any advice is appreciated!
