you're 19...shoot, you should have a few porn vids under your belt by now...

f'n a...he's staring at you, trying to catch glimpses of you through a window, he tells you he broke up with gf, he didn't wanna hear "sorry" from you but rather something else, his mates know what's up with him (thus the "get a room"), he's playful with you, he's checking you out, he's kissing you...

yeah, you're right...he's not in to you at all. in fact, i think those are all universal signs of repulsion...

[don't get your panties in bunch...just roll with the sarcasm...]
