I agree that if a client feels abandoned, then they were abandoned. Could be literal, or could be virtual... e.g. when a therapist withdraws emotionally or otherwise alters their persona.

Therapists should not get a pass when they cause a client to feel abandoned or betrayed, just because the therapist meant well or couldn't avoid some circumstance.

If a therapist asks for your trust, opens pandora's box, then announces something in their life necessitates shutting you down on some level... then they have s**t the bed as i see it.
