As our little boat struggles forward my wife and I are co-captains. And we have an awesome little crew of kids, dogs, cats, and even fish. All attached via rigging and lifelines.
I believe a father and a mother should agree to parent 50/50 forever. If things happen and that agreement changes in their future together, at least they started out with their hearts and vows in the right place.
She has played all her trump cards and she's still not happy. She's remarried and she's still not happy. She might not ever be happy. That's no longer my problem.
I believe that our child-centered lifestyle and choices allowed us to let go of the marriage in favor of the kids' welfare. Regardless of who blinked first in the marriage, in the end, it is a mutual decision.
