That’s a kind of response that would make me feel unsafe in the relationship. If she’s not being honest in order to get a reaction from you, I consider that manipulation and game playing. Even if you were engaging in that behavior first. I don’t feel like it sets a good example for healthy relationship patterns, regardless of her intention.

I think when a client talks about leaving, it’s a therapist’s responsibility to say honestly whether they do/don’t agree but emphasize that they are there in case they change their mind and will support them with whatever decision they ultimately make. Anything else seems disingenuous, inconsistent, and unstable.

In thinking about it - the scenario reminds me a little bit of abandonment reinactment. Therapist pulls the stable base from under the client, and watches the client’s panicked scramble response to hold on for dear life. At worst, playing into the therapist’s own need to be needed.
