Sorry to here that, it hurts thinking of the pain that would have been.
Lost my wife to cancer many years ago and was a tragic thing for me and my kids.
I did CPR on her for a half hour before the ambulance got to us and the next day had to make the decision to take her off the life support machine and let her die.
I will never remarry because can't handle the pain of loosing one wife and doing it again with another.
Wow that had to be really tough to go through that and have to make that decision. It was the kindest thing though Fred and showed how much you loved her and not let her suffer any longer. Took a lot of guts I say.
