You have some very challenging questions. I don't know that I have a great answer, but I do agree with some of the responses for you. What is best for d3. Consult a with a good L for legal advice as it will help in making wise decisions and help for future decisions by the courts. Hopefully in your state the courts favor the well being of the kids above all eles. I am fortunate in that aspect as well as my L is very focused on that. I am not one to give advice on exposure as I have no experience for that but there are many vets here on the forums that can hopefull give you the goods and bads.
I continue to pray for you and your family and hope that you are able to find information that can help you make the best decision.
Be sure to look out for you and d3 above all else.
