It may well be that most clients find that therapists do not leave them during a rupture.

But I think it's still a realistic possibility that clients need to consider, because it DOES happen. I never expected it to happen to me -- and then it did. Perhaps considering the possibility is enough for a client to take reasonable precautions inside themself not to trust too much, or something. Especially if there are no other good options. But there still may well be an uncertainty there.

It may well be more likely to happen with some clients than others. Perhaps it's something about the client and/or the kinds of client-therapist dynamics that some of us tend to get into -- transference/countertransference at some very deep levels or something.

But none of that changes fact that it can and does happen, and can be devastating when it does.
