So this one girl is better than a billion other women in the world? Jesus. Move on bro'. If you really want her, make her jealous. Talk to other women in the class-room. Let her see you around other women, talking, playing and teasing. She'll eventually get jealous and try to chase you back. Trust me, works everytime. Or, If she's really demented in the head of jealousy, she might hurt herself ( yeah, It really happens. ) If that doesn't work. Move on.
