I think I still like him but he makes things so complicated and unrealistic! Please help!!?

Ok so it's summer for me and I'm going into 7th grade! And last year was my 1st year at my school but for all my friends it wasn't because there's an elementry skool connected to it. And last year was kinda the 1st year I started to like guys. But in 5th grade I had those cutesy little kid crushes but never did anything about it! So I became pretty good friends with this guy named matt, he was the guy I would always hangout with after school when no one else was there, or our group of friends was there too but we really got to no each other during those times. (my skool has an after skool program for mid skoolers) he would always ask me questions about myself like, when my birthday was, what my middle name is, where I live! And just things like that. Then I started to notice him looking at me in class, and I'm used to it! Half the 6th grade guys liked me! (literally!!! Gross!!!) so it really didnt bother me. But then I started liking him, and I totally thought he liked me, and we just became like best friends. We txted every single day! We walked to parks and stores after skool. And stuff like that. But one day I missed skool cuz I was sick and like 2 minutes after skool was out he txted me asking me y I wasn't there and if I was ok. A d this lead onto him telling me he kinda likes me. (and u no 6th grade guys when they say "kinda" it means alot!) so the next few days he tells my friend he likes me alot and she tells me but he gets mad at her 4 telling me and it's awkward. But we still txt everyday and stuff. And then the next few days we don't really talk or hangout or anything! And I still like him. And so one day I over hear him saying he doesn't like anybody but he stares at me in class and might I mention ( he is kinda the class clown so whenever he cracks a joke he looks at me waiting for my reaction) and he still does that!! it's like I don't exist to him. So now it's summer and I miss him. I miss joking around! I miss our random convos what should I do??????
