**I think from an outsider, more societal point of view, the family breakup is worse.**
I tend to agree with you. My mom and my daughters have expienced miscarriages/death of a child. It is heart wrenching to say the least.
But the loss of a family is community/state/nation wrenching — children have no positive model on which to base their parenting skills when a divorce occurs (provided the divorce did not happen because of abuse to the children or spouse.)
Yes, I would agree that sometimes divorce does cause a portion of the child to die sometimes. And then they never recover the part that was lost.
