I think she is haphazard and careless with you; I don't believe she thinks before she speaks and/or acts sometimes (which is dangerous in a T). Both emails you have posted about recently are clear examples of that.
I think it was very brave of you to tell her that it wasn't working; I am not sure how this became about a lack of commitment from you. And although I understand her concern about SH, I don't see how such an ultimatum is helpful.
I don't think she is the kind of T you need in order to be able to do the kind of therapy she is asking you to commit to. I think you can find a T much better suited to help you!
