I would joke that playing golf was a long term commitment to marriage. Ooops. I've played two rounds this year way down from last year. While at the club, I'd get all sad because of what was missing. I no longer follow the sport or care about what Tiger Woods does. It was all for him it seems.
You're right, the side benefit of divorce is doing what you want when you want it. Not that it makes up for the loss of the relationship, it provides momentum to rebuild a life in as healthy and positive a manner possible.
