It depends on the type of guy, I suppose. I don't really get your question, though, why 'half a year'?
More than likely, I presume.
it may mean that he likes you and now you started at him you two may become boyfriend and girlfriend
it means the guy should only be focused on his first girlfriend and not staring at another girl.
He's embarrassed; when he saw you looking he probably thought you'd caught him, so now he's afraid to look at you because he doesn't want to get caught.
girl this means the guy totally likes you! congrats! or he is interested in other things like maybe your body so look out don't let anyone take advantage at you good luck!3)
Its normally because he likes her, if he doesn't like her then he is beginning to like her.
almost everyday for the ones who have it
It means that he wants to ask you out and he secretly likes you, but he is too afraid of rejection.
It almost never is. It's probably a stalker that you running into everyday. Or perhaps it could just be that you need similar things at similar times. Or you like a lot of the same places and things.
2 times everyday?
oooooh, you like each other oooooooooh!!!!!!
She stared becoming famous in Good Times!
