I'm guessing the legal stuff is not helping the OP. When I was caught up in a horrible rupture with a therapist, legal concerns were irrelevant. In my experience majority of what happens in therapy is left to therapist and client to sort out.

Ethics codes in the US (OP is not in the US, BTW) leave almost everything to the discretion of the therapist and thus are basically meaningless. Emotional abuse takes many forms and none are codified other than the few obvious ones. Therefore it might be appropriate for a client to push back, to preserve their sanity and well-being. In my situation, there was nobody advocating for me except me. Clients have few protections. Therapists have plenty.

I also think invoking legal protections for therapists is something of a joke (unless the client is posing a legitimate threat), given that most of them skip meaningful informed consent up front.
