Just wanted to add that I totally understand the urge. It took me a LONG time to really get over what STBX thought of me. And it was a little by little thing.
I think men care so much about what their woman thinks about them that it's easy to get to a spot where we don't know what to do anymore if it's not vying for their approval. And it is so devastating to be in a position where nothing you can do is good enough.
What helped me- I had a team of professionals. IC, DB coach, and an L. Any major decisions were run by 2-3 of those individuals. That way I knew I wasn't making emotional decisions when it came to parenting, communication, finances, etc. When STBX started spewing stuff about how 'unfair' I was being, it made it easier to dismiss knowing 3/3 of my professionals had insisted I take those steps and I was merely 'following orders'.
That, and after a few months I found out the truth. It's unfortunate but I had to demote STBX to a person beneath my attention, because she isn't treating me well enough to keep her place in my mind. The heart takes a little longer, but it does follow.
