“ With the act of marriage the situation frequently changes fundamentally. The marriage contract gives each partner the exclusive possession of the other's bo dy, feelings, and care. Nobody has to be won over any more, because love has become something one has, a property. The two cease to make the effort to be lovable and to produce love, hence they become boring, and hence their beauty disappears. They are disappointed and puzzled. Are they not the same persons any more? With the act of marriage the situation frequently changes fundamentally. The marriage contract gives each partner the exclusive possession of the other's body, feelings, and care. Nobody has to be won over any more, because love has become something one has, a property. The two cease to make the effort to be lovable and to produce love, hence they become boring, and hence their beauty disappears. They are disappointed and puzzled. Are they not the same persons any more? Did they make a mistake in the first place? Each usually seeks the cause of the change in the other and feels defrauded. What they do not see is that they no longer are the same people they were when they were in love with each other; that the error that one can have love has led them to cease loving. Now, instead of loving each other, they settle for owning together what they have: money , social standing, a home, children. Thus, in some cases, the marriage initiated on the basis of love becomes transformed into a friendly ownership, a corporation in which the two egotism are pooled into one: that of the family.Did they make a mistake in the first place?
