Wow almost a month since posted and lots of developments... so 50/50 is where we ended up and seems to be working OK. The house definitely feels a little emptier now with all her stuff gone and D10 out half the time.
I think the biggest change, and while some may not agree, is that I've decided to take a more gentle approach with W.
I had dinner with a friend who went through a divorce a number of years ago and he brought up a good point - with kids involved you are going to be involved with this person for the rest of your live, you can have it be pleasant or you can have it where everything is a fight.
This doesn't mean I'm caving to her every whim and am still keeping some healthy distance and my boundaries, but I'm also not going out of my way to ignore her. We had a good conversation on finances over the weekend and even exchanged some non logistical texts and conversations.
In my mind and heart these niceties will either pave the way for R or at least a future where we can "get along" for the benefit of D10.
