Mammela, we can logically assume that children from divorce homes are more likely to learn from their parents mistakes than to merely copy their parents patterns of behaviour, in the same way that most people naturally learn from their past mistakes and its consequences.
On the other hand, children from dysfunctional homes that their parents have not gotten divorced but have also not worked out the issues between them, are more likely to get divorced from their own marriages, as they may tend to copy their parent/parents behaviour while not having the advantage of learning from the consequences of divorce, unlike children from actually divorced homes who have likely internalized that learning experience the hard way, like you noted.
