Nightsky, grief and confusion seems painful I'm sorry you are having a rough time.
Maybe your T realized that he isn't helping you any longer and that he is under obligation to terminate if he doesn't feel it is in your best interest to continue with him... It sure sucks but sometimes having final closure is better than always having doubts... should I go back? should I find someone else?
Maybe after the grief mellows...the clean break will be a positive thing
