Rabbit Remembered, one story from: Licks of Love: Short Stories and a Sequel, Rabbit Remembered

Harry "Rabbit" Angstrom is 26, has a job selling kitchen gadgets, and is married to Janice, his former high school girlfriend.They have a two-year-old son named Nelson, and live in Mount Judge, a suburb of Brewer,Pennsylvania. He believes that his marriage is a failure and that something is missing from his life. Having been a basketball star in high school, Harry finds middle-class family life unsatisfying. On the spur of the moment, he decides to drive south in an attempt to escape. He soon returns home, however, where he visits his old basketball coach, Marty Tothero.
Tothero introduces Rabbit to Ruth Leonard, who is a part-time prostitute, and they begin a three month affair. During this time, Janice moves back into her parents' house. Rabbit, jealous of a past fling between Ruth and a local man, forces Ruth into submitting to fellatio (presented here as a degrading sex act), and on the same night Janice goes into labor. Rabbit leaves Ruth and rushes to the hospital.
Janice gives birth to a baby girl, whom she and Rabbit name Rebecca June. Rabbit returns to live with his wife, and accepts a job at his father-in-law's car dealership. Rabbit attends church one morning, and fueled by the flirtatious overtones of the minister's wife, he tries to get his wife to have sex with him. When she refuses, and makes a comment about the "whore" that Rabbit lived with for 3 months, Rabbit runs out. The next morning Janice, while drunk and afraid that Rabbit has left for good, accidentally drowns their infant daughter in the bath. When Rabbit returns for the funeral, he refuses to take the blame for the baby's death, ultimately running away once more. He returns to Ruth and finds her pregnant. She puts forward an ultimatum: file for divorce or she will get an abortion. Unable to make a decision, Rabbit runs away once more, leaving the novel's ending in midair.
