Does he like me back?

He's my friend. We always talks to me and teases me. He always asks something from me, always plays with my things.He keeps on asking me nonsense questions.He always notices me when I p by him at the corridor. Many people said that "we we're together" but it's not true because he has a crush on somebody else(and it's not me).They always teases us that we're together and I don't know why. Even my friends teases me with him. One time I was igned to wash the dishes with his one friend. He keeps on "asking me are we together?".Many people say that we are together. Does he like me?
