Im in the same situation and have been thinking exactly the same. I'm not proud of myself, but I do give some thought to what I would do when the worst occurs, and short of me getting run over by a bus, I will be living a considerable time without my wife. I keep coming back to the fact that the odds are against me given the divorce rates and that I'd struggle with spending the proceeds of assets my wife helped me acquire on another woman. My biggest worry is that I will confuse missing my wife with a desire for companionship and do something stupid. As someone else posted, being with the wrong person is infinitely worse than being alone. Hopefully I can increase time spent with family (kids and grandkids) to help combat the loneliness that is inevitable.
On a less negative note, I've promised myself I'll watch a couple of episodes of "Snapped" before I will get into another relationship. It's a show on Oxygen channel described as "Each episode of this true-crime reality series examines a different felon, usually a female, who has committed murder or attempted murder. The victim is usually the perpetrator's partner."
