Prayers going out to you and Duke. I'm certain that whatever decision you make, it will be the one that is right for you and Duke. Altho there is never a right or wrong, or black or white, there is what you feel in your heart, the direction you choose to take, and you should never question or second guess yourself once you have made that decision. Don't be troubled by the "what ifs", since life is full of them.
And always remember that miracles do happen.
