I totally get your need for re-assurance. I'm always finding some little thing that my T does that I can interpret as rejection, not wanting to see me again, etc.. Knowing that I tend to do that helps me tone it down a little. Are you sure your T is pulling back? You said her life has been very hectic, etc, and I think it is such a good thing that you can recognize that - don't blame yourself! I don't know you, but I know I don't hate you :-) , so don't you either. Feel better!
P.S. Gee, I don't feel "spent" at all!
