Hi Sally :Hugs:,
Your T sounds completely unreasonable at the moment, perhaps something about this situation is triggering him but shouldn't he as the therapist be able to recognise this and work through it with you?
This is not your fault and if he would admit his mistakes maybe this rupture could be repaired. Its gone on too long now and needs to be sorted out, i am glad you are looking after yourself though Sally by removing yourself from the situation for a while. Perhaps you could write him an email to explain it all, or cope the above post and send it to him?
