I think most couples WANT that ideal fairy tale marriage where they are still chasing each other lustfully around the house in their wheelchairs 60 years after the ceremony...I think most folks contemplating marriage WANT for it to be a lifelong thing. I think none of them WANT it to end in divorce..I just think that most look at the world around them and recognize divorce as a SIGNIFICANT possibility, even a probability. I think that most HOPE that they are one of those that make it that long, but I think that most face up to the fact that most aren't going to actually last that long.
