<human>: Can you give me the gist of the text in a nutshell?

I've never had a long term relationship. Never had a girlfriend, just dated two other girls in the past, both didn't end up going anywhere real. I'm really bad at seeing the "signs" and don't really know how to keep a conversation exciting unless I like what we're talking about. However, I met this girl that I find super attractive both looks and personality wise about 3 months ago. We study together at the same University and I met her at an orientation for an extracurricular organization. 

We text semi-regularly when she's not busy with her extracurricular stuff. When we do text, we have really nice long conversations, but sometimes we go a few days without talking because she gets really busy.

I've had about two lunch hang outs and took her out to brunch once. Just recently I took her on a real date. Just her and I, a really sweet romantic movie and dinner. (Cliché, I know but what can I say) I made it clear that I was taking her on a date and not just a hangout. Got to put my arm around her at the movies but she didn't seem to like or dislike it.

Which brings me to my questions: How can I tell if she likes me? I know for sure that she knows I like her. Although I've never said it straight to her, I'm kind of an open book when it comes to stuff like this. Should I ask her how "we" are? Should I tell her straight that I like her? I'm probably not going to see her regularly until next year because classes are out for the winter break and I really don't want to tell her I like her over the phone or anything like that.

She's super nice to everyone no matter who they are. That's why I'm questioning if she likes me back because she's just the type of girl who's always bubbly and happy.

I really don't want to scare her off by saying something stupid. Any advice Relationship gurus?
<bot>: Into this girl that's nice to everyone so I can't really tell if she likes me back. Taken her out to a nice date once. Text semi-regularly.
