She wants you to do this for you. She's allowing you to reach the place where you can process on your own between sessions and not need that contact between sessions. She's chosen that path of not dictating that to you, but instead allowing you to reach that place on your own. But you DO rely on those emails and they DO make you more attached to her. I know you don't think so, but you have only on rare occasions been able to delay that gratification of contact between sessions.
