I am very sorry for your loss. My wife and I have been married for 30 years and as we age I realize that it is unlikely that we will die at the same time so one of us will eventually be in your situation. You are very lucky though. The only reason you are in so much pain is because of the joy she brought you for so many years. Many people never get to experience this. Just think of all the X-wife stories you read here. Based on what my grandfather told me when he lost my grandmother it's going to take time. I wish you peace.
