Sorry you are feeling so crushed , but she did it in your best interest . She , in my oppinion should have been drilling this or setting this boundary a long time ago and kept it firm, reminding you that although she cares for you , it was always going to be client relationship. Never allowed you to call her mom, even if by mistake, ( enabling) in residential it was different. She cares alot for you and finally drew the the line, but , it had become so blurry, that it has left you longing and confused and angry.
