Liars [paperback] by Steven Gillis

Eric McCanus is a novelist with the misfortune of having written his one great book when he was young. Struggling to write more, recently divorced, while still missing his ex-wife, Eric becomes convinced that happy relationships are unsustainable. Determined to prove the accuracy of his theory, Eric stumbles upon a seemingly perfect couple at the market. Convinced the marriage of Cara and Matt can’t be as successful as it appears, Eric does what he can to break them apart. What follows is a psychological and philosophical comedy of errors. Liars is an exploration of love, relationships, and human interaction, a madcap romp through the vestiges of modern affairs, revolving around five characters, each spun drunk on the batterings of love while attempting to sustain themselves in a false world.
