please help!! boy troubles!

Ellen
I really like this guy and as soon as I saw him like a month ago I can't stop thinking about him! And we smile at eachother whenever we see eachother around school but, he's 2 years younger than me and I feel like that might stop anything happening, I really want to message him but I end up just staring at the blank messanger for hours! 
So help ,should I message him?!?
