"We began, without thinking of it, to be inseparable, to share, as it were, our existence in common; and feeling that we were not only necessary, but sufficient, for each other, we accustomed ourselves to think of nothing that was foreign to us, to limit our happiness and all our desires to that possession of each other, which was, perhaps, unique of its kind amongst human beings, which, as I have said, was not love, but a more real possession, which, without being dependent upon the senses, sex, age or personal appearance, was concerned with all that which makes one what one is, and which one can only lose by ceasing to exist."
