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.
