Search Results: girl sending mixed signals

So I got rejected by this girl a while back, but ever since then she keeps sending me mixed signals that keep getting stronger. Sometimes we'll go out to lunch and she'll touch my feet or brush up to me, and laugh at practically everything I say. Other times I'll be walking out of class and she'll be outside my classroom (she never used to be). Of course I'll go over an talk because that's just who I am, and she'll say she's studying for a class, but the building I take classes in is out of her way and away from the previous and upcoming class of hers. Whenever we see each other unexpectedly or in groups she always makes an effort to come over and just hangs out around me until I have to leave. I'm not sure if this means to much either, but I am also her 'best friend' on snapchat consistently (maybe it means she just thinks of me as her best friend haha). Should I make a move, drop it, or wait it out?
