<human>: Condense the text into a few key points

I've just started college and this girl has been spending a fair bit of time with me. She gave me her number, we've texted etc. She approached me first, something which hasn't happened at all with anyone else at college. We got talking and for some reason I feel relaxed around her. (I started college on anxiety medication, since I've been friendly with her I haven't needed it)

As the weeks have passed by, she's made efforts to talk to me, suggesting we meet to study at least once a week, begged me to sit next to her in class, told her friends about me (who she said wondered where she was going all the time) and taken me to see her flat.

I can't tell if she's just being nice or if she genuinely likes me. But I've been in similar situations before with a girl - she acted exactly the same, but I never made a move. I regret that a lot. I thought she was being kind, perhaps sympathetic and at times I wondered why she would even like me.

Which is kind of why there's a problem here. Do I make a move and risk cutting her off as a friend or do I not make a move and risk losing another great girl to my self doubt?

Well if life were so easy.

She has a boyfriend who she's only ever mentioned once, and she didn't even make a big deal of it. Before anyone says "move on", I would but my options are limited.
<bot>: Girl shows signs of liking me, but she has a boyfriend. My lack of confidence in this area is sending me mad
