I remember talking with my wife a number of times about friends who were having marital difficulties and saying that if they werent happy, what was the sense of staying together, life was too short, they deserved to be happy, and if splitting accomplished that feat, then so be it.
I only agree with that everyone deserves to be happy. I think the theory of splitting to accomplish that feat is a big 'ol myth.
I agree with you on #2, D sets up a cycle with our children.
I also agree with you on #3. Nobody wins, per se. However, I also believe we can use the adversity to become better people. I am not even close to the same person I was 15 months ago. Maybe that's just GAL'ing.
We're killing ourselves as society for sure with no-fault D.
I think we have to play the hand we're dealt, though. There's a lot we can learn. We can become better people. We can work on our own happiness.
