If this guy doesn't like you back, I would advice you to stay away from him, at least until you've realized/accepted the fact that you and him aren't gonna be dating. Otherwise, it will break your heart to see him be with others, maybe even getting a girlfriend. Trust me, I've been there! And if he knows you still love him, and you keep staying near him, which someone's suggesting, he'll see as a stalker (been there, too
). It's not possible to be friends with someone you're in love with. And as NearokA also said, you're pretty, you'll find someone.
