I'll bet that some kids from a divorced family come out better than some in a miserable marriage or over protecting parents.
That thought consoles people, but the evidence really doesn't support it. Kids don't really care how their parents feel about each other. They care how their parents feel about THEM. And the way you show you love them is to stay with them no matter what.
There are tons of kids who grow up in single family homes.Or divorced homes. They survive, just fine. There are no parents fighting, creating angst.
I doubt many of us had " the perfect childhood".
I came from a solid, loving home but my marriage ended in bitter, quarreling divorce, in which I got out in order to put an end to the fighting in front of the kids.
I have heard only a little from my children of how my divorce was for them, but I imagine it must be, to a helpless and dependent child, like their house being torn apart, shingle-by-shingle and board-by-board.
