You're doing great RSG. I think the rule of updating her at the end of the day is the way to go, especially when you and S are hanging out. Stealing that one for when D and I are out and about together.
Keep building up that confidence. I can tell from reading your posts that you've built a ton of it as you've done better and better in single dad mode. Your W has to be seeing that confidence, which is a good thing. Regardless, keep up the focus on you and your S because you're on a great path there!
