What do you think??? give me ur honest opinion -im so confused?

theres this dude i like and we used to chat whenever we could but then i kinda stopped(cuz i started getting nervous talkin to him)..like i always said hi but ive stopped sitting next to him in cl, stopped paying as much attention to him etc. im pretty sure he knows i like him now, since my friend made it obvious, but a bit after i stopped talking to him, he stopped talking to me completely. he acted like i didnt exist and so i tried makin conv wit him but he just reply wit a single word and got bak to whatever he was doing. now he talks to all my friends infront of me and doesnt chat with me. sometimes it almost looks like hes talking to my friends just to show me hes not talking to me. some of his friends and mine think he likes me but i heard that the last girl he liked, a girl he was really good friends with, he would talk to her whenever he could. so im not sure if he just really doesnt like me and i did something wrong or if maybe he likes..(in my dreams..right??) tell me wut you guys/girls think. tho..wut i heard is that he recently started likin someone...(sad T_T..lol)
