I realized today that she probably never dealt with our divorce emotionally. She just ran from everything
Joe my sitch is different than your's but I'm closing in on a year separated from WW and what you said right there...
When I was just at my IC before Xmas she said to me "I don't believe your WW has dealt with the separation, ending of the relationship and likely never will". That completely blew me away! I mean mouth open, "how in the H" could that be. I say that to you because I think you are very wise to be thinking that you need to "roll back the clocks" so to speak much further than just you and XW getting into R or piecing.
I just wanted to say from personal experience your insights are wise and I like your approach to taking your approach with her more as a slow simmer and less like a hot boil.
