Issues like this involving the "frame" and the housekeeping boundary details of therapy come out of no where and feel like an ambush. They are the meaty part of therapy sometimes, and working through this with your therapist and repairing the relationship might bond you even more. Maybe he just forgot to talk to you about it bc it isn't happening for 2 months ? I get how you feel, because I am freaking out bc my T changed his billing and it reads point of sale from a state on a different coast than mine on my credit card statements, a state in which he used to live. I am petrified he is moving back there and lying to me that he isn't . However, I have been through these panics and resolutions many times with him, so I am more hopeful and less reacting. For sure your T should have talked to you personally before you received a letter like that! I hope he owns it and apologizes. I hope there is a time that works for both of you. So sorry for how sad and lost you feel today; it is a shock to be reminded it isn't as personal as it feels at times- it is and it isn't.
