Joshua Ferris, "The Unnamed"

They say it takes a long time to really get to know somebody. They say a good marriage requires work. They say it's important to change alongside your partner to avoid growing apart. They talk about patience, sacrifice, compromise, tolerance. It seems the goal of these bearers of conventional wisdom is to get back to zero. They would have you underwater, tethered by chains to the bow of a ship full of treasure now sunk, struggling to free yourself to make it to the surface. With luck he will free himself, too, and then you can bob along together, scanning the horizon for some hint of land. They say boredom sets in, passion dissipates, idiosyncrasies start to grate, and the same problems repeat themselves. Why do you do it? Security, family, companionship. Ideally you do it for love. There's something they don't elaborate on. They just say the word and you're supposed to know what it means, and after twenty years of marriage, you are held up as exemplars of that simple foundation, love, upon which (with sweeping arms) all this is built. But don't let appearances fool you. That couple with twenty years still fights, they still go to bed angry, they still let days pass without --

The trouble with these cheap bromides, she thought, is that they don't capture the half of it.
