Search Results: fooling around with a girl

I'm a sophmore in high school and I keep getting mixed messages from this guy. I can't figure out if he's really into me or it's he's just fooling around or if he's just a total flirt. He's in 2 of my classes and he's quiet the looker according to myself and other girls in class who have come to me and confessed that they think he's really attractive. He sits behind me in both classes and some days he'll fool around and mess with my hair and hum and sing and do all these little things to get my attention and make me laugh and he's be totally friendly and open with me. Then I'll have days where i go to talk to him and he just really seems like he doesn't give a shit about talking to me and I'm totally annoying him? Then i'll have days when i try to talk to him he acts as if i'm annoying him but he'll still do all those little things he does for my attention? Then the other day i got to school and i was walking to class and ran into to him and we started walking g together. It was just me and him and it was really nice because we were talking and laughing and he seemed totally open with me and he seemed like he was totally into me and then later that same day he doesn't ignore me but he just seems like really isn't interested in talking to me. What do all these mixed messages mean? Is he into me or is he just fooling around or is he just trying to figure out if he's into me or not or is he just simply a flirt. I never see him flirt around ith anyone else except for this one girl who he also sometimes jokes around with in a class that a share with him but besides that i never really see him flirting with any other girls.
