Divorce generally sucks. Whether you are splitting on good terms, or because you've really come to hate each other, I think it's usually tough to do the break. When my first wife and I divorced, she was already involved with another man, and I had frequent fantasies about ripping off one of his arms and beating him to death with it.
On the other hand, after the divorce, my ex and I had more frequent and way better sex than we had the last year or so of our marriage. And it lasted for years, even after she remarried. So, I guess I won a pretty nice consolation prize.
