Why do girls obsess about their crushes?

Why do girls think about their crushes for long periods of time, like months or even years?

If I like a girl, I just approach her. If unsuccessful, I move on to the next girl. If you’re actually not going to approach the person you like, why bother thinking about him or asking questions on GAG about the situation?
