I think when she brings up legal stuff, I will have an "opening statement" memorized. I will say something like...
"I understand this is what you want. I understand you feel our problems are unsolvable. I want you to know I forgive you for everything that has happened and really want to thank you for opening my eyes to the past and the Whole New World ahead(referencing Aladdin our 1st date). I understand you feel this is best and we need to do what is best for our 5D. I understand you feel I try to be perfect. In this case, we need strive for it to do what is in the very best interest of our 5D."
Perhaps, I can mention counseling, dvd's, retreats later if the what would it do to help comment comes out of her mouth again.
