excile, it's far too soon to consider Sandi's rules counter productive. There's a period where nothing at all will make a difference. Your W seems to be playing you the way they all do right now. Don't fall for the "friends" stuff either thinking you've got a way back in.
You've got to pull away entirely. No messaging, no answers. Be brief on anything that has to do with the kids.
There are many L's that will give you a free consult, you should start looking right now to learn your rights. Find the right fit. It might be an eye opening experience.
Do I miss the dumb little things about being married? Shared experiences over a lifetime that nobody else knows or would understand? You bet. However, you need to protect yourself, and grow yourself. If not you, for your kids. There's going to be a lot more turbulence before you get to cruising altitude.
