One other thing ....so you know I am in the middle of my divorce....
Do what is fair and just. Do not think that throwing yourself on her sword will snap het out of it. Nope. Chances are it will not. You do not have to be a dic# ....just be firm. She wants this then she should deal with the aftermath.
Good luck
