He doenst notice me (im invisible)

Okay i like this guy. He isnt ugly or cute hes just whatever but i have a crush on him. I guess its cuz there really arent any guys at my school yet to actually like. Anyways he knows me because like my brother and my cuzen are close frends with his brother and they sometimes hang out with my crush too. But even though he knows me like that and cuz i used to be in his english class last year ( i sat rite in bak of him he used to talk to me sometimes but he doesnt remember) he still acts like im not there like im invisible. He hangs out with these other group of girls and some guys and he says hi to them when he sees them and talks to them but he never says hi to me. I have talked to him be4 about him asking him if hes mad at me or somthing that hes not talking to me he said no im not and stuff. Like once a month hell say somthign to me or not even though his loker is close to mine.

What can i do for him to talk to me and notice me withought making it obvious that i like him?

In all honesty .. if you don't talk to him now, then you can't possibly know if you truely like him because you don't 'really' know him! I know what it is to have crushes on people that "didn't notice me" me as well.

and if he ignores you now ... then you know he probably isn't the best choice of guys. so my advice is to let the crush wear off and find somebody who 'sees' you and likes you for you!!
