A beautiful woman I recently met had an interesting theory on divorce that I hadn't thought about. Since we are all living longer, that by about 50 or so, if you've been in a long marriage as we have both been, you realize that you hopefully have many good years left and do I really want to live the rest of my life with someone who doesn't make me that happy. It's no more about until death do us part anymore.....
Having said that, it was easier to stay in a committed relationship with my wife all those years, than it was to stay in a committed relationship with my stereo gear. Was always quite the playa with my stereo gear :-)
