A love affair is like a short story--it has a beginning, a middle, and an end. The beginning was easy, the middle might drag, invaded by commonplace, but the end, instead of being decisive and well knit with that element of revelatory surprise as a well-written story should be, it usually dissipated in a succession of messy and humiliating anticlimaxes.
I try to turn a written thing, when I'm in trouble with it, into a spoken thing: I start imagining what I would say to someone if I were trying to tell the story or make the argument.
