From my limited experience as a teenage guy (I try to avoid being an annoying prick) the guy's either an annoying prick, in general, he dislikes you for some reason, he has a mental health issue, he craves attention in any form or he might have a thing for you (probably what you wanted to hear).
Of course this is all speculation, which is to be expected when you ask an arbitrary question.
Comment: The answer is excellent, because it covers all the bases. The last answer (has a thing for you) is the most likely, but it also means that he's a clueless idiot with zero social skills, and even if he does have a thing for you - is that want you want? From there , it's your move.
Run from the stalker! What do you mean he keeps your hair?
that he absolutly hates you.
If Your A Girl It Means "Someones" In Love. If Your A Boy. Not Answering That Question Cause Im Not.
When a boy keeps telling you about his girlfriend it probably means he really likes his girlfriend and likes to talk about her, but the only way to know for sure is to ask him.
maybe or he might just think your weird
Either that or you've really pissed him off.
It means the same thing as usual; he probably doesn't like you.
disturbing
You have answered your own question. He is trying to get your attention.
He either likes you or is trying to annoy you.
He likes you
It probably means that he likes you, in some way shape or form.
