Hey Irish - just catching up. Don't have much to offer besides what's already been said here. Wow, she's lost at sea.
The way you communicate the texting conversations with your W, you can almost see the pops in her brain going off that trigger her switches in topic. Sounds like she's trying to get you to mend her relationship with your daughters, she doesn't want to do it herself.
Of course there are some lessons to learn on how to deal with her better, and I'm sure you'll see whatever that is for yourself. Being a LBS requires so much damn restraint. Even when it's time to say something after keeping your mouth shut for so long, it takes focus to figure out what to say (at least for me). Getting through the fog with a truth dart can be hit-and-miss.
I think you handled it like a pro. Not the victory anybody wants, but pat yourself on the back. Rest, brother.
