Probably because he likes you but doesn't know how to say it. Just ask him about it. Hes just jealous that your talking to some guy that isn't him.
most likely this other guy who is staring at you feels jealousy or is interested in what he sees .
It means he need to see a physician. He needs to get a life!
Most likely
she stares at guys but sort of long not long long just long
it means that he likes you, but he doesn't want to make it obvious. also it means that he got a little jelous that u like another guy. trust me on this one iv'e had experience with boyzz :)
if he slaps you on the but and if he stares at you
As a guy, i admit i do this. When a guy stares at a girls butt, it means he is attracted to you. When he stares at your lips, he is hinting that he wants to kiss. I don't know if you are in a relationship with this guy, but if you are, take the risk when he stares at your lips and kiss him! Guys make the first move a lot, but they love it when the girl does!
He thinks you are ugly, or there is another option, which is he has dirty mental images involving you.
If he stares, and quickly looks away when he looks at you, then yes. If he just stares, and stares, and stares and doesn't even flinch when you look at him, then no.
if you look at him and he looks at you back.
He regretted his choice
it means they are really good friends or the guy likes her. i would say that the guy likes her.
well anyone could answer that lolzzz he likes u!! or thinks ur cute (:
