Rob,
I so sorry for you, you really did not deserve this sadness. But think about it, she is willing to separate the dogs just for spite. She seems totally incapable of caring for anything other than herself. She didn't want to put any effort into saving her marriage no matter how many times you gave her the chance. She put all her efforts into pleasing herself with other men. She is acting like a spoiled child. Perhaps you should just not deal with her for some time and just do what the papers say .She is really awful to split up the dogs, it will be so hard on them. I think she just enjoys hurting you.
