Why porn is the death knell for a happy marriage: Married couples who view adult material double the risk of divorce

The Daily Mail reports:

Married couples who watch pornography almost double their risk of divorce, researchers said yesterday.

But viewing adult films or images comes at a price, with the researchers saying that women who start looking at porn while married are almost three times more likely to want a divorce.
