If I was in your shoes I would write out all of my thoughts about the boundary transgressions, and being terminated via text, but leave my anger (and passive aggressive jabs) largely out of it, and I would take it to my therapy session and read it to force me to confront the issues head on. Of course, I also trust my therapist so we might be in a fundamentally different starting point. If in that session I didn't have a good gut feeling about his response, if I felt like we were at an impasse that couldn't be fixed, I would thank him and say goodbye. I would probably then have a total mental breakdown, and go crying back to my old therapist, the cold quiet blank slate and have a couple twice weekly sessions crying and rambling on about the whole ordeal. I would get a massage and cry through it. Eventually I would come out the other end, hopefully with a new and better therapist. I wouldn't file a complaint. I would try to weigh the good and the bad, because there is good and bad in everyone and everything. There has been a lot good in my therapy, and some bad, certainly if my therapist snapped at me in text I would be devastated, but I wouldn't want it take away all of the nice things he's said. Actually I would worry about him... it would be out of character, I'd wonder is he ok? What was going on with him to get that reaction, is his kid sick, is he grieving some kind of loss, did something I say really hurt him that much? I would assume it had more to do with him than with me, either that or I really said something to step on his toes. I would need to know, I would be compelled to at least tell him how I experienced it.

It's hard to judge your complex relationship with your therapist, which has evolved over hours and hours based on a couple paragraphs I've hastily read. None of us can possibly understand the complexity of your full relationship, and your therapist is just a human, obviously not perfect and has screwed some stuff up, but who knows what's up with her. But if I squeezed your current details into my therapy, above is how I would hope to respond.
