A&A, my parents divorced when I was 16, my youngest sibling was 5. IN our case, dad was very physically abusive (so that's what messed me and my sibs up), and there was a collective sigh of relief for the older ones of us... It was hard for the first few years, but we've generally doing ok.
But you know what, alot of things, other than divorce can screw up a kid. So it's just amatter of looking at all the factors involved.
