I've noticed a subtle shift at the end of our sessions too...I never really considered it before, but she could be disengaging. I've always thought she was just trying to help me transition out of session and back to my day.

But I notice it more in whether or not she hugs me...sometimes she seems hesitant to hug me (maybe she wants me to initiate?). Other times, she moves toward me to initiate a hug.

I wonder what your T would say if you asked about this?
