I suggest not taking anything a therapist says as a promise. If a therapist says they are not leaving - the best it can be is that they have no active plans at the moment to do so.

This is one one the most "we adore therapist" sites I have ever read. Good lord, there is more therapist fawning going on here than possibly even in therapy school. And as for changing - no one has to do so, and from my experience a good number of the therapists should.
