Good Faith by Jane Smiley

Joe Stratford, who sells nice houses in a beautiful place, and whose not very amicable divorce is over, is ready for his life to begin again. It is 1982, morning in America, and temptation is everywhere. And, as Marcus Burns (Joe's new friend from New York) says, the old rules are ready to be broken. By turns poignant, insightful, and outrageous, it is Jane Smiley at her funniest and most slyly astute.
