A love story can never be about full possession. The happy marriage, the requited love, the desire that never dims—these are lucky eventualites but they aren’t love stories. Love stories depend on disappointment, on unequal births and feuding families, on matrimonial boredom and at least one cold heart. Love stories, nearly without exception, give love a bad name.

We value love not because it’s stronger than death but because it’s weaker. Say what you want about love: death will finish it. You will not go on loving in the grave, not in any physical way that will at all resemble love as we know it on earth. The perishable nature of love is what gives love its importance in our lives. If it were endless, if it were on tap, love wouldn’t hit us the way it does.

And we certainly wouldn’t write about it.
