<human>: Give me a shortened version of the text

To preface this, I should say that I have very little experience with women, hence why I am asking here for some advice.

I met my crush through a mutual friend late last year and after barely mustering the courage to ask her out we went on one date before being apart for winter break. Even though I didn't end up making a move I thought the date went well and we agreed to have a second one after the break. 

So last week I asked her if she wanted to go out again and she said yes. The morning before the date however she said she needed a rain check on it as she wasn't feeling well. 

I should also mention that we have hung out quite often in a large group setting and it seems like she only is comfortable spending time with me in that setting. This seems like a sign that she wants to be friends but I also figure it could be that she is just shy around guys she likes.

This all brings me to my question, which is would it be a bad idea to simply give her a call and say something like "Hey I just wanted to clear something up between us. I'm attracted to you and am interested in being more than friends. Do you want the same?" Or would that just put her in an uncomfortable situation and make things more awkward between us?
<bot>: I can't tell if my crush is just nervous around me or if she isn't interested in me in a romantic sense. Is it a bad idea to simply ask if she is interested in me or would that just make her uncomfortable?
