Does she like me or not?

Here are examples! Sit in cl and I'll look over at her and notice she is staring at me, she emailed me and "noticed" I wasn't in cl and called me a slacker after calling her one for missing a cl, she told me she liked my confidence and sense of humor, but we have exchanged numbers and hardly talk outside of cl except earlier when we would talk through email. We are in a biology cl and whenever we have lab she will come over to my microscope to check out what I have up and she'll just nudge me aside, but will also check out others but be more cautious or careful about going up to them
