You can move out and away. The child stays, until you get a court order specifying custody. Otherwise you will be liable for charges of "custodial interference" (kidnapping).
Your wife could not "sign away" the child without your consent in most states. If the child is not living with you then you might as well get a divorce. If the child is living with you then you might as well get a divorce and apply for sole custody.
You need an attorney for proper legal advice for your Jurisdiction.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
