When I was divorced, my kids were 9 and 4. Their mother and I divided the children's time 50-50. Now the kids are grown and on their own. It is my observation that EVERYTHING mentioned in this article is 100% right on. It is amazing to see a study which actually gets it right.
By the way, I remarried, created a moral, Christian home, and had 2 more kids which were also 5 years apart, just like the first two. There was one boy and one girl each time. These two are now 8 and 13. Just like the article said, the results with these two are excellent and reflect consistent rearing by two parents who love and support each other. Once again, based on first hand knowledge, the findings in this article are exactly right.
Maybe you are a better parent now. Maybe the problem with your children from the first marriage was less the divorce than the kind of parents you and your wife were.
Actually if you look at large sibships in intact families you can see a variety of adjustedness,,some seem better adjusted, happier, more functional than others,,,within the same intact family.
I suspect divorce is harmful for many children. But I also know intact hideous marriages that do not serve children or parents well. I wouldn't suggest divorce be lightly taken, it usually isnt when kids are involved. But I don't think two people are always doing the best thing when they stay "for the sake of the children".
