I for one could not go to a therapist who is a blank screen. On the other hand, anger is inappropriate and more about her than you. The only exception I would make is if you hurt her in some way which I doubt.

My T is pretty expressive and I like that. He rarely tells me how he feels internally about our relationship but I can tell through his comments back to me what he is probably feeling.

Honestly, look into other therapists and at least go to a consultation and make your decision then.

I wouldn't tolerate anger from her, I've got plenty of that myself
