Your list looks great, sho! And, as usual, you're getting awesome pointers here on how to minimize contact with W in-home.
The ONLY thing I would add is this: when you deliver information to your W about where you're taking the kids ... or when you tell her you're going out ... do not act mad or bothered. Do not sulk. Do not be patronizing about anything. (I'm not AT ALL saying you are; I just know how easy it is to swing from "taking a stand" and "detaching" to being a douche and coming across as controlling and/or pouty. At least that's always easy for ME. Lol.)
Stay focused on that list up there: confident and happy BUT ALSO strong, convicted and determined.
