A girl told a boy that she was rejected, and the boy said, please don't talk to me in the future. What does that mean?

Girls like boys and their confession is rejected. The boy also said, please don't talk to me in the future. If you confess to a boy, and the boy says such a thing, it proves that the boy doesn't like you either, and he doesn't have a crush on you at all. He said that because you said your confession and it was rejected. He said such a thing to make you stay away from him in the future and leave him alone.
