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

We're both in our senior year of high school, I met her through one of my classes and started talking to her through there. I'm really interested in her, and I've kinda got the feeling she might be as well, but I'm not sure. We talk everyday in class, we've walked around the hallways together a handful of times and sat together during some of the mandatory high school stuff like pep rallies and etc. I finally manned up and asked her to a movie for last weekend, but set it up so it would have been in a group setting with a few mutual friends so it wouldn't be super awkward initially. She said she wanted to go but ended up having to cancel last minute because of her parents. That leaves me with my question-- where do I go with this now? Should I try getting her number, or wait a few weeks and ask to hang out again for something else? And, should I ask to hang out in a group setting or what? Once I figure that out, at what point does it go from friends hanging out outside of school to "a thing"? I'm really oblivious when it comes to this stuff so any kind of insight is appreciated.
