Does he like me, or am I just crazy?PLEASE ANSWER!?

Hello, I'm Kelsey. I'm in year eight; and have really started to develop feelings for a boy named Jesiah.We've always been acquaintances, but lately have been becoming much better friends. I've actually began to start thinking he might even like me back! I mean, he talks to me WAY more often, always try's to make me laugh, talks to me diffrent then any other girl, has talked to me on the internet, and has asked me to sit beside him in the computer lab. He also says " bye kels!" at the end of the day, almost every day. He knows i like him, but we haven't talked about it at all. Also; the other day his friend Sanel hollered something at me when i was walking to cl. But all I could make out was me and Jesiah's names. I asked him to repeat it and no matter what Sanel won't. Yesterday, while I was in changing for gym, I menchained Jesiah. & this girl said" yeah, he knows you like him" , then my friend asked if he like me back and she just flat out said "no". That was one of the first times i've ever cried over a boy! Was he just saying that? Or is he just trying to become better friends? Please be honest with what you think!& somebody who just put's a sentence and what not will NOT get best answer! thanks!
