So apart from the council of cold showers or "let the good times roll," is there any good advice for those traversing the relational wilderness? Religion and morality contribute ideals of character. But social science also indicates some rough, practical wisdom.
First, while it may not be realistic to maintain the connection between marriage and sex, it remains essential to maintain the connection between marriage and childbearing. Marriage is the most effective institution to bind two parents for a long period in the common enterprise of raising a child -- particularly encouraging fathers to invest time and attention in the lives of their children. And the fatherless are some of the most disadvantaged, betrayed people in our society, prone to delinquency, poverty and academic failure. Cohabitation is no place for children.
Second, the age of first marriage is important to marital survival and happiness. Teen marriage is generally a bad idea, with much higher rates of divorce. Romeo and Juliet were, in fact, young fools. Later marriage has been one of the reasons for declining national divorce rates. But this does not mean the later the better. Divorce rates trend downward until leveling off in the early 20s. But people who marry after 27 tend to have less happy marriages -- perhaps because partners are set in their ways or have unrealistically high standards. The marital sweet spot seems to be in the early to mid 20s.
Third, having a series of low-commitment relationships does not bode well for later marital commitment. Some of this expresses pre-existing traits -- people who already have a "nontraditional" view of commitment are less likely to be committed in marriage. But there is also evidence, according to Wilcox, that multiple failed relationships can "poison one's view of the opposite sex." Serial cohabitation trains people for divorce. In contrast, cohabitation among people who are engaged seems to have no adverse effect on eventual marriage.
There is little use in preaching against a hurricane of social change. But the delay of marriage creates moral, emotional and practical complications. The challenge, as always, is to humanize change. The answer, even in the relational wasteland, is responsibility, commitment and sacrifice for the sake of children.
