Some thoughts.

Why should we honour those that die upon the field of battle? A man may show as reckless a courage in entering into the abyss of himself.

W.B. Yeats

The anxiety of loving Chloe was in part the anxiety of being in a position where the cause of my happiness might so easily vanish, where she might suddenly lose interest, die, or marry another. At the height of love, there appeared a temptation to end the relationship prematurely, so that either Chloe or I could play at being the executioner, rather than see the other partner, or habit, or familiarity end things. We were sometimes seized by an urge (manifested in our arguments about nothing) to kill our love affair before it had reached its natural end, a murder committed not out of hatred, but out of an excess of love - or rather, out of the fear that an excess of love may bring. Lovers may kill their own love story only because they are unable to tolerate the uncertainty, the sheer risk, that their experiment in happiness has delivered.
