I so in love and im hating it!?

ive known this kid since first grade. hes pretty popular in the town i live in and hes only 13 (hes an awesome golfer). well we were friends in 1st-4th grade and we dated a little in 5th grade and again in 6th grade. but i was obsessive and i wanted to hear nothing but his voice but because of me being like this, we broke up. now im in 7th grade and hes with the popular kids. im not. i still have major feelings for him and i think im in love for the first time. to me it makes sense. but im not sure if he feels the same. he probably thinks im not the same because when i talk to him, i use my flirty voice and he points out "why are you talking like that?" i have changed since 1st grade. im really starting to think im in love but how can i tell him? hes the type who is part emo and makes weird looks at something if he doesnt like it. im worried ill embarr myself. ive even had dreams of me kissing him!
