I agree that both Edward and Grace were flawed. They were married 29 years and now, when he is basically a walking crypt keeper of a man, he decided to opt for a woman who “touched his arm” and he fell in love? What a sniveling specter of an emotionally crippled, gutless man. Grace, for her part, was committed to the marriage regardless of how alone she felt. She cried out for help and desired connection but he was happy to get on his laptop and wiki his stupid life away. Sorry, both had a part in the collapse of this marriage and the idea of “happiness” as often portrayed in contemporary film and parlance is shallow, fleeting, and a futile pursuit. Happiness, is work. You must work at it. Running to the arms of someone else who is unhappy or lonely is a practice in futility. I have a lot more I could say about that. One thing I will say is that the collateral damage that children, mutual friends and society as a whole endure is devastating because we pursue “happiness” which usually means, “my own selfish desire”. There is something to be said for suffering even through an unhealthy marriage. Many things can be fixed if they are worked on. Unfortunately we give up and give in and never really try. It’s much easier to give up.
