Today we like to think that marriage is a free choice based on love: that we freely choose whom to marry and that we do so, not so much for survival or social advantage, but for love. The invention of marriage for love inverted the old relationship between love and marriage. In the past, marriage was sacred, and love, if it existed at all, was a consequence of marriage; today, love is sacred and marriage is secondary. But now marriage appears to be becoming increasingly superfluous. For the past forty years or so, the number of weddings has been declining, the number of divorces exploding and the number of unmarried individuals and couples growing, while single-parent families are becoming more numerous. Love has triumphed over marriage but now it is destroying it from inside. So has the ideal of marriage for love failed, and has love finally been liberated from the shackles of marriage?
