Sorry to hear things are so hard right now. Why do you think he wants to end therapy? Has he ever mentioned therapy ending? Has he shared that this is his approach to ending things with clients? Most good therapists I think would not consciously this route as it would likely be very confusing and damaging for the client. Is it possible he is making a lot of bad decisions or mistakes lately that are causing ruptures.

My therapist has said they would just tell me if they felt that maybe needed to try something different which they did.

At the end of you post it sounds like you have stopped your therapy? Did you just decide not to go back?
