Did Robert accept what they had
He could have looked her up after her husband passed, but he never did. I keep wondering if he liked things just as they panned out. If he wanted to be with her and loved her so much then why not join her. Was he still respecting her relationship with the husband. He could have lived far away but as time went by from the way the movie unfolds one would think he would have kept tabs on her. He may have become ill for years or just at this point in his life felt he could no longer measure up. How would he compare 4 days with a life of another man.
This movie had a ton of points where you have to fill in the blanks with whatever you felt happened.
