Why he looks at me but never talks? His friends act strange and stare at me and sometimes often laugh when I'm around?

My classmate looks at me but in the start when I caught him staring, he looked away. I had a feeling that he and his friends notice me. He talked to me once and never talked again. I have noticed that his best friend laughs when I say something but he doesn't. When he and I are alone, like at a place when there's nobody, he keeps looking at me but when he is with his friends he does this for 1 time and not more than that. If I say something, I notice him hearing to me. Is he into me? If yes then why doesn't he approach me?
