Does this girl have a crush on me?

She may or may not like you, there is not enough info, there never is with girls. They are very mysterious, learn that now. ;) Really, it's about what you want to do. Mostly, it sounds like she wants to date, or your friend zoned and she just wants to hang out. Also, don't date her if you have a heavy schedule. You do not want to just squeeze her in.
