I don't know all of what's going on but it all sounds a bit self-destructive to me. Now, instead of being actively engaged in therapy, it's been derailed and all attention is focused on this T who is being portrayed as unreasonable, unstable, etc. Maybe so, a lot of them are, but they can still be effective therapists. When you cancel sessions and start playing cat and mouse games and things like that you are exhibiting resistance to treatment. That alone is enough to terminate. Why should she waste her time or yours. It sounds like whatever you said in your email backed her into a corner and she told you straight up she didn't know where to go from there. That's as honest an answer you're going to get. That's the reason.
