I know for me, all that 'self work' while some was ties into the M and mistakes I made ... the core stuff was things about me that not only affected my M, but also other relationships.
I lean more towards being a bit mysterious about what you learned, what you are dealing with ... one could even just tell the W the DB go-to "I have been making some progress, I am happy with the results thus far, I still have some ways to go ... given the chance I would do several things differently" .... if prodded then you can just list one or two things you would do differently in your M ... this is all YOUR perspective on yourself that might align up with legit complaints she had. None of this is aimed towards her, nor your M per-say ... just self reflective stuff. The less details you give, the more she can think about it and connect her own dots.
Sounds like your IC is on the ball ... it truly is all about YOU right now.
