He has a girlfriend but flirts with me...?

okay so I have liked him before and I told him so the flirting kinda stopped I mean wow he was all over me. I'm in 8th grade by the way. anyway we still flirt now and I like him again but.hes got a gf! but he said he likes someone else and I'm just hoping it's me. I have 2 classes with him we talk and flirt in both of them.so now we don't flirt as much has we used too but we still do.and in one of thoses classes is his best friend and he used to scream to the whole class that he liked me and he never once denied it, but he stopped one day whe he said I know who (his name) likes and I looked at him and he was looking right at me, and the guy I like didn't say anything.and when he was done playing at the football game he wanted me to help him with sis stuff so I did I asked him where he was sitting he said by you. so I took his stuff over by me but my friend was between us and she know I like him ugh! and he went to go sit by some other friends and he texts me asking to watch his stuff, and we were texting the whole time.oh and once I got out of my seat(I sit next to him) and when I passed him he was like ohhh katie, like he was checking me out. tust me I can say a lot more but based on that do you think he likes me? or what?
