I can't help but notice how the roles in your sitch have now almost completely reversed. You are not the LBS and she the WAS. Strange. Not that good for you I guess, but in terms of you applying the DB principals and really dropping a lot of the initial guilt you felt for being the "cheater", it applies.
You seem to be saying all the LBS stuff, and her the WAS stuff. It's as textbook as all the rest of our sitches, it just started out flipped.
So, welcome to the other side. While you still haven't earned your way out of your marriage, you have earned your way to feel kinship with us, on this side of the fence (as if you didn't already, lol).
Sorry you have been having a hard time with W. She seems really hell-bent on sticking it to you right now. Hopefully that will pass.
