Lizisace, would you be comfortable explaining a little more about the no progress during the first 9 months? For example, how do you define progress? Did you talk to your T about what you would consider progress, what your goals are?
I suppose if you had asked before to do whatever she needed to get alters to front, that would at least align with your stated goals. If you had no such agreement, her actions were pretty opposite of what's recommended for treating trauma.
9 months of no progress actually stood out for me more than what sounds like clumsy, manipulative, aggressive choices. I'd recommend moving on from that alone.
A test for me would be, if you decide to meet again (up to you!), whether she apologizes or not when you describe how specific choices she made were upsetting, frightening, etc. An ethical, mature T will apologize for mistakes, even if completely unintentional ones (like wearing red before you tell her that's a trigger for you). And they will promise (or promise to try) not to repeat them.
This is a fundamental part of any therapeutic relationship. Heck, it's fundamental to any relationship in life. An apology wouldn't suggest you should continue working with her, but it would be nice. My T apologzes every one or two sessions, they're simple but indicate she gets it.
Labeling your response as "avoidant behavior' was also manipulative and felt like a power play to me while reading it.
