Best advice I can give you is to keep doing what your doing. There might be an OM that you don't know about or a potential OM that she is thinking about. Its good to have hope, but think of her as a loss. Nothing you say will convince her otherwise. Your W will have to find things out the hard way much like other WS talked about on this forum. If she ask for D, then tell her to present you with the documents. And if it looks fair, then give her what she wants. All resistance will just upset her more.
