I'm going to reject a friend when they talk to me and then I'm going to ghost our friendship.
Why will you ghost your friend?
I don't want him to know why I rejected him.
Ghosting your buddy to end the relationship is going to make your friend pretty upset. You are better off being honest and just telling them directly.
No, this is the best way I can handle it.
This is not a great habit to get into though when it comes to ending relationships. Your friend I am sure would appreciate some sort of closure.
