There is this guy but he and this girl......help?

I like this guy a whole lot and we met when we were 13 I'm barely 15 now but...neway so when we first met hes was a real goof! and a frend. but we didnt live in the same town and raely saw eachother we met through a frend. So then last summer I moved to the same town and we went to the same church and I found out we were gonna be going to the same highschool. So during the summer me and my sister hungout with his sisters and he hung around. And at the time he seemed like a real frend but i had had a crush on him since day one. It seemed lik he paid attention to me. When ever something was wrong he knew and always asked wut was up. and we talked and were cool. But then we started highschool and the first day i didnt see him at all and he asked where i wuz at church. But wen we started seeing eachother at skool. I tried talking to him and he just did the head move that ment hey and kept walkin. n eventually he stopped talkin 2 me really. he did the head move everytym i saw him tho.......
