I am not sure what the guy is complaining about. He afterall married a woman that he even had issues of getting along with before they even made that lifelong commitment. Usually, you make sure you're comfortable with that person before you commit yourself, but he knew there were issues before they even got married
Another point, they both thought by going to church, everything would be solved

That is so childish in any standard! You see issues with the person that you about to marry, you either quit it or buy more time to figure that person out. They both ignored all signals that showed their incompatibilities, and here he is upset about what happened in all of those years
He is bragging about having a long sleep in his first day after the divorce. I doubt it. I think he can't get over her and get her out of his mind. Usually, when you divorce someone, you're done with that person and never look back unless of course you would love her or him (depending on your gender) to be back in your life. By talking about her, it is obvious he did not want the divorce but perhaps did not have a chance.
But then these couple got divorced after 28 years?

If they live together for 28 years, I think there is something else that he is not telling. Perhaps he was no longer a man to her, she met a younger guy, and she got rid off him. Being a California girl - the home of liberalism - says a lot about her
