Hugs, if wanted. It could be that you need to fully (or at least somewhat) grieve the loss of Ex T before you can really move forward with other work. Would it be possible to work with Temp T for a bit, then resume work with the other T when you feel you're ready?

I just know when I had the big rupture with my former marriage counselor a few years ago, I had to do a lot of talking and working through that with my individual T before I could do much other work. I think at the time, my T was bothered that I spent so much time on ex-MC, but now I think he gets that I needed to process the loss (and he talks about it as "grieving").
