The Divorce Generation

A child of divorced parents, and a product of a generation of divorce-riddled families, Susan Gregory Thomas swore she'd never divorce.  Absolutely swore it.  She even hints that she chose her husband based on a cold calculation that together they could weather any storm:
I had married the kindest, most stable person I'd ever known to ensure that our children would never know anything of the void of my own childhood...My husband and I made the happiest, most comfy nest possible. We worked as a team; we loved our kids; we did everything right, better than right. And yet divorce came. In spite of everything.
I don't know what makes a good marriage. I am inclined to think that Mark Twain was right when he wrote in an 1894 journal: "No man or woman really knows what perfect love is until they have been married a quarter of a century." But I did know something about divorce, and I wanted—and my former husband wanted—to do it as "well" as possible. 
But, aside from some statistics we may not have seen before, is her essay on the subject insightful at all?  Or is it just a self-deluded attempt to justify the unique failures of our generation over and against our parents'?  My friends whose parents divorced insist that the process always hurts kids.  Is there any reason to think that we're doing it so much better at the beginning of this century than they were at the end of the last as to render the process painless for all involved - especially the children?  There's little evidence of that in Gregory's account.  But I guess there wouldn't be - it's her story.  We probably need to wait another few years until her children start blogging about the experience, or publish their own memoirs.
I have yet to meet the divorced mother or father who feels like a good parent, who professes to being happier with how their children are now being raised. Many of us have ended up inflicting pain on our children, which we did everything to avoid. 
But we have not had our parents' divorces either. We can only hope that in this, we have done it differently in the right way.
So sad, in the first and third senses of the word.
