I use to pray my parents would divorce, because of the non stop fighting. But they never did.
But the evidence shows that, on balance, divorce results in more anguish than bad marriages. It also does not end the bitterness felt by a parent who retains custody, or another parent who is left out in the cold. Divorce is like abortion: a bad solution to a bad problem. That is because usually the divorcing couple are,usually, thinking only of themselves. That is also the case in bad marriages.
