Hi SD, if it makes you feel any better, I had much of the same attitude at the beginning of my sitch. The blame, the personality swings, the entitlement, the denial.
It's not easy, but you already know what has to be done, you've said as much. Leave what's outta your hands to God.
Don't mind read or assume too much if you can avoid it. Plunging into an actual D or S could create a new crisis in her mind and her actions could surprise you in a positive way. Not that you should revolve your hopes around that.
