Muddle, Once again, you only know what your W tells you happens in therapy! Anais Nin said (or wrote) "we don't see things the way they are, we see them the way we are". That is your W! But to explore why the A is happening and why she is so stuck on it is a good thing, isn't it? No T will tell her to stop the A, go back to her H and work out her M. A good T will help her explore until she gets to the point where she wants to do so. That is then her choice. The T'also only hears what your W tells her about how you care for her needs, not your side/viewpoint. Forget her and her stupid T, it's a cheeseless tunnel for you. Work on what you can, forget the rest.
