Boy, delete it.

The boy is not generous enough to make friends by admitting failure. But understandably, many boys feel that since there is no result, they should not intersect. Now that you have rejected him, don't have any contact. It is easy for him to think that you are separated. You want to be friends, but he doesn't think so. So, if you don't want to give each other any possible misunderstanding, then don't have anything to do with it.
