Well, it depends. If you know you were looking bad and being rude or annoying or weird he is probaly looking at you because you are weird to him. But!! If you look fine and are being nice, it probaly means the guy is checking you out and is interested!
It could mean a variety of things such as he is interested in you, it could be coincidence that he is looking in your direction but in a daze and not really looking at you, or for whatever reason of his own.
It means nothing. He may not even be looking at you at all but in your direction. Just because someone looks in your direction doesn't mean they are looking at your or interested. People look at people because that is what we do.
not all the time it means he likes you... some men are just pigs.
Well it's quite normal for people to look at you but if you catch him staring at you multiple times then he may possibly like you
He thinks your HOT!
It means he likes you.
Girls, when a guy does this it might mean he likes you but he might be sizing you up... What I mean by this that put simply he thinks your cute. Also if he does this nonstop He absolutely does like you or if hes staring at lets say your butt... he's a pervert.
It may very well mean that a drugged guy is looking at you
Facebook.
That he wants to "get to know you better."
They have the same interests
he is starstruck
Nothing. He is a nice guy.
it means she likes him
Not necessarily.
He's admiring from afar...
It means he's trying to subtly tell you that he loves his girlfriend, and any advance you make is a sign of disrespect to him and her.
He is simply a guy! guys do that unfortunately!!
