Winterrose, this sounds like the sort of thing that therapists are supposed to use their supervision for. I think it is within your rights to ask him if he has supervision for his problem with your case. Is he consulting with another therapist about his difficulties? If he isn't, I would be very worried, because it sounds like he is not handling his countertransference well at all. I hope you will ask him this very important question. You deserve an answer.

I found his statements to you about the pain and hurt you have caused him and your dangerous relationship to not be therapeutic at all. It sounds to me like he is losing it. Who's the patient here?

Has he told you that you "broke" the relationship or is that your feeling?

It sounds like you have both a therapist and a pdoc. Is the pdoc just for meds? If you feel comfortable with the therapist, maybe you could just switch to a new pdoc for meds and continue productive therapy with the therapist.

Good luck. Very difficult situation.
