Sorry to hear about your daughter. That is hard. We could hash what you did wrong, or right, but its done.
When you see her you have to acting "as if" if you want this M. She needs justifcation for her A, and your feeding that to her with a spoon. She knows she isn't doing well by the kids, she even seperated in her email pre seperation time vs. now. That shows she knows she isn't mom now.
But don't respond to her negatives. You know who can push my buttons better then anyone in the world, my W. Same for all of us, you have to swallow pride sometimes.
When you talk to her, let her know your listening, repeat what she said and the give some type of understanding or at least you heard what she said. Not necessarily agreeing but letting her know your listening.
I guess back to a beginners mind and think what about what you want.
