If you want to get a nice guy to like you, you usually start off as friends. If he says yeah, then don't make it seem like you're obsessed with him. But if he says no, get flirty, try harder, but not too extreme, and see if you can make him change. And if that doesn't work, lay off. Remain friendly, not stalker-like. Creepy isn't attractive to anyone. If they are looking at you every now and then, then you are doing great!
If you are too shy, when he's near, talk with a lot of friends and laugh. But not too loud. Act like you're having fun. Make sure you don't give off a fake impression. Just be yourself. NEVER change yourself in any way for a guy. If he looks at you then it's a sign of paying attention. Good luck!
P.S. If the guy ignores you when he's with his friends, let him go! ;)
