I'm sorry that you are having to experience this! I don't know your T so its hard to know why she is doing this to you, but speaking from my personal experience with T's and boundaries, I really believe this situation could of been handled with more care and should of been.
Whenever I overstep my T's boundaries ( which I have done a lot) I am always gently reminded of there existence and why they exist, we talk about it, what was happening for me and then together we work out how best to work on it. My t always says that boundaries are not punishments but merely guidelines for healthy relationships.

If I was you I would maybe write a letter that you could bring with you to your session regarding this matter and how it made you feel, I'd even ask your t if maybe she could go through what is healthy and unhealthy boundaries to her and come up with some agreed upon boundaries so they are clear and you understand them so that your not left in the dark and then hit with new ones. I think your t owes you that especially seeing as though the therapeutic relationship is a partnership & is there so you can learn and be open without fearing punishment
