I can relate to this. Maybe she is employing you to work through it on your own? I thought T's were our place away from real life. As in different from friends and family who expect you to 'get over it' or can't be supportive because of their own issues..

My T has really backed off to allow me to work things out without him. It's painful. When it changes. Seems inevitable, unfortunately. Expecially when you don't feel ready or are left in the dark about the changes.

I'd ask your T next time you see her what's up and the reasoning for her silence.
