Frankly, I can't imagine choosing to live so far away from my children. How do you opt to live in another state - hell, another continent - without your kids? Nicole Kidman has the money and resources to live wherever she chooses.
I don't like Tom OR Nicole, so I have no bias towards either one of them, but if someone tried to keep my kids away from me it would be over my dead body. I can guarantee that my kids would never call another woman "mom".
