Do Crushes Ever Go Away?

What do you think? Do crushes ever go away? I'm interested in how others handle this, because mine never do. Once I've had a crush on someone, they're there forever. Not that I'd ever act on them, or that it affects my day-to-day-life in any way, but my heart is filled with hundreds of little baby torches I carry for cute boys the world over. What is that? How do you get rid of them? How do you make them go away? I don't get it. If I saw someone online who I had a crush on when I was in seventh grade, I still get that tingly feeling in my heart. If they blow me off again, my little heart gets yet another little crack in it. How do I make this stop? Why am I such a silly girl?
