ask him???

I have liked this guy for many years, since ano 4. I'm fourteen now!!! he found out I like him in ano 6. During ano 7 I was to shy to talk to him and we weren't in any of each other classes :(!!! My coração always stops beating when he's near. we don't talk much but we give each other eye contact. He would catch mine, and I would catch his. Now this ano I'm only in 2 of his classes!!! We have begun to talk a bit and we once smiled at each other.... I don't know how to control these feelings! you probably be thinking I'm young and know nothing about love.....but i can't explain what I'm going though. To most girls, he isn't the best looking guy, but to me he is perfect in every way. I really want to confess....but I'm scared that he won't speak to me??? I have held on to these feelings for so long........none of my friends understand and i can never talk about this to my parents (will think I'm nuts and laugh at me)....so I'm hope one of you to please help me!!! i can't get him out of my head and i really want to confess...And how should i say it??? Thanks so much!!! from the bottom of my coração it means a lot to me....<3
