You will find that if you faithfully change everything on this "list" of hers, she will suddenly just have a new list for you.
It's a cheeseless tunnel.
I forget who it is over on the MLC forum, who's been helping CD Bear on his thread, but they refer to trying to focus on the walkaway/wayward/MLC spouse's charges that "sting." Meaning, those things that YOU, in your heart, really ARE things you need to change, whether they be to try to save THIS relationship or to take into your NEXT one.
If you focus on what a wayward spouse SAYS they need from you, you'll find it's a pretty fogged-out list, and they'll either just add to it, or tell you they don't believe you've really changed.
