David, welcome to our little club here. I'm sorry you've found yourself here, but I'm glad you found us.
You are doing a lot of good things. You're doing a great job. Keep it up. That feeling is amazing when you realize it's not your job to make your W happy, isn't it? Ahhh, the freedom of not walking on eggshells anymore.
Realize this whole thing a big roller coaster. What you are doing right now will help you to smooth out some of the hills.
LP has a point - it DOES seem like almost all of our wayward spouses are following the same script. It does seem there must be a downloadable manual somewhere. I dunno, marriagebusting.com?
