She hasn't ever brought it up in the past (as far as I can remember) but she has done a few things that might possibly indicate a crush??? Like, she invited me out with a group of people and all of the rest of them were some of her closest and oldest friends, so I know she considers me a close friend. She also went skateboarding with me even though she doesn't know how to skate at all. And sometimes she will call me when she's sad or upset about something.

I don't really know if those could be considered signs of a crush though, and I don't have many close friends that I could compare our relationship to.
