One could say that we can have such relationships without involving our families; we do not need our families to force us to be nice and considerate toward our spouses. But the reality is that human nature always “reverts to the mean”. At the beginning of a romantic relationship we can treat the other person with the greatest consideration. But once the honeymoon is over, the couple start to take each other more and more for granted and start to do less and less for each other. This is something that has been experienced by most people, who may have at first thought they would be the exception to the rule. The point of socially integrating a romantic relationship into society is to extend the honeymoon-level of consideration to the period that comes after the honeymoon. That is the magic that social integration achieves and that is almost impossible to achieve without it.
