I think many Ts would see a difference between a completed therapy and a client who periodically checks in, and an incomplete therapy and a client who, for whatever reason, only seeks out contact when in crisis--and then leaves again after a few sessions. Many Ts make a strong distinction between therapy and crisis counseling. I'm not sure that a T would see a pattern until a pattern emerged. She absolutely should have given a clear and full explanation in this last meeting. But we don't know what was discussed that there was disagreement about. The statement about therapy relationships sometimes ending is presented as the conclusion of a discussion. That sounds to me like something a T might say when there is an unresolvable disagreement about how to proceed going forward, and so ending is the only option.
