maybe you gave him too much to do justice to over the phone and he's wanting you to come in and talk. I haven't found that Ts have a boundary against ever talking about other Ts - it can be very relevant, as you'd relate your experience of that relationship the same as you would relate your experience of a parent, a co worker, etc.

don't worry. The idea of having gone for a long time to talk about surgeryand chemo etc and this time to talk about recovery, made me smile. I hope it goes great
