Robx is dead on with his points, blame will be coming your way, so acknowledge it in the fashion as Robx has said. I agree on staying in the HOME, even a lawyer will tell you don't move out. Use the term Family Home, it is a place for your family not just a house.
It is not meant to be mean, it is just distant and dark. It is a line that can be crossed easily, I know I have. So, you withdraw and you dettach. Think about you getting a life, act as if she is no longer in your life. Easy, hell no! But as people have said, it is for you.
