Dear Amy: A few years ago, friends of many years ghosted me, for no apparent reason. This was painful and confusing. I moved on, maintaining friendships with others in what had been our common social group. Now, as suddenly as I was exiled years ago, my former friends, “The Ghosters,” have begun including me once again in invitations. I’m not sure how to respond, although I guess the stress I am feeling right now indicates that I have a clear choice? Can you offer your advice? — Ghosted Dear Ghosted: The act of “ghosting” (cutting someone off suddenly and without explanation) is intended to protect the perpetrator from consequences.
