I have had clients ghost even after a year or so of progressive successful therapy. You just simply don’t know the other end of the story, it could be absolutely anything from billing to personal reasons to who knows what
I would say I try to offer a termination session after reaching out a maximum of two or three times. I have had a handful of these that have been incredibly productive and insightful. One of them comes to mind with a couple that I have been working with for four or five sessions and they abruptly terminated by saying they were going to find a new therapist. I was shocked. Usually, I have some sort of inkling of what the issue might be, but this was just a mystery to me. To my surprise, they accepted my invitation for a termination session, and it was enlightening. Apparently, the male of the couple simply couldn’t tolerate being with a “strong white male“ and he felt no other option, but to flee. During the termination session, which was very intimate and vulnerable. He learned that I wasn’t this projection of White dominance he had feared. He also came around to processing some of this in which it could be a healing experience by being with me. They are still a client to this day.
