Confused much?please help!(very long)?

okay well long story short so this doesnt go on forever.me and my bestfriend and a few other people went to a home football game.just like every other friday night.so EVERYONE is always there.so i went out with this kid and we have so much in commen.hes short im short we have the same personality,and alot more.so i went out with him twice 2 years ago.then we broke up.then he liked me once last year,but we didnt go out.and this year,im in 8th grade,he told my best friend all these things.they were having general conversation when he brought up somthing.he said that he still has feelings for me and that he still really really likes me.he has only kissed one girl and that was me.he said it was the best kiss ever.and he said that he has always liked me and he tried moving on.and he just cant find anyone like me.and i feel the same exact way.he was saying that he wants to go out with me because he has always liked me and in homeroom yesterday he wanted to give me a hug,but i didnt give him one.the reason why is because i thought he didnt like me so i didnt want to make it obvious that i still have feelings for him because i didnt know he still liked me.so he also said he knows i dont like him even though i do.and he thinks he will never have a chance with me.he said he has never felt the way he did when he went out with any other girl excpt me.and i feel the same way.what exactly should i do?should i kinda show him that i like him?i wasnt even expecing this becuase i thought he didnt like me and that i was just stupid since i like him soooooooooooooooooooo much and im basically crazy for him.but he actually feels the exact way that i did for like 3 years!im so excited right now too!but i dont know what to do.he still thinks i dont like him.how should i show him that i do?thanks in advanced!
