Hmm...I think her boundaries, although a little strict and definitely painful, are normal for some T's. It sounds like she really wants you to be comfortable on your own, and although I get that, I know that approach wouldn't work for me. I have spent my life alone, and since my T knows that, she makes sure to emphasize that she is always available to me when I feel like I want to or need to talk to her.

Are these boundaries you are willing to deal with? If so, it's time to accept them and only bend them when necessary. If not, then consider finding a T whose boundaries work better with what you need.
