A couple times, I have told my marriage counselor that he seems to "get me" and what I need better than my individual T. He's said things like, he only knows a few therapists who are better than my T, and he's not one of them. So not quite to the same level as what your T was saying, but similar. It was difficult for me, too. Because if *I* think he's good, then it feels invalidating for him to say things like my T is a better therapist than him or that he doesn't understand me as well as I think he does. Self-deprecation is one of his things in general though. I mean, I guess I wouldn't want a therapist who was really arrogant, who thought they had all the answers. But still, if I think he's helping me and I think he's good--shouldn't that be what counts, not his opinion of himself in comparison with other T's?

So, in other words, I understand. Maybe your T is worried she's not helping you? Or, more likely, she doesn't want to be what keeps you from making the move. So she's saying you can find someone better there, to keep from holding you back from something that you think is good for you (moving).
