Ummm, because you have an intimate and close relationship with her? Because you have shared intensely private and painful things with her that you have not shared with other people before? Because she has been so helpful to you and cares about you? I think there are many reasons to "ache" for a therapist that are related to one's very real relationship with her. I know it may be different for you, but just thought I would say that there is nothing inconsistent with aching for and missing a "regular woman." If you are close to that "regular woman," then you may very well ache.
