Thanks for asking, nutfarmer. Just an update. I'm feeling a bit better. Have been more firm in my dealings with her. Last two counseling sessions have been more productive. She's taking small steps-calling, being home on time, emailing me, being a more engaged mother, texting, etc. But I'm not an idiot, and I'm not going to simply relax on this.
One of my feelings lately is that I think her idealized rship with Mr Nooner is coming back to earth. I don't know if it's dying a natural death, or what, but I'm sensing that something is not going perfectly there.
One thing I'm noticing also is that the more I work through this, the stronger I am in dealing with her crap. I'm getting in great shape, talking to a DB coach weekly, connecting with old friends, etc and it really does help fill the void.
Thats the latest. I'll quit while I'm ahead. Thanks to all for your continued help. And Happy Turkey Day tomorrow.
