Come Back to Me - Carolyn Astfalk

After his wife, Jamie, kicks him out, Alan moves in with his brother and sister-in-law, who are expecting a baby. As the days turn to months, the prospect of a reunion grows dimmer, and Alan is left to pick up the pieces of his broken marriage while bunking alongside blissfully happy newlyweds.
Megan, Jamie’s friend, is privy to both Jamie’s and Alan’s private woes, meeting Jamie to lend an ear and occupying a barstool next to Alan. Megan’s dissatisfaction with her own life—meaningless hookups, a brother who’s found Jesus, and an increasingly awkward relationship with Jamie and Alan—grows.
Alan comes to his sister-in-law’s aid when she goes into labor, forcing him to act with long-overdue maturity. Meanwhile, through a conversation with her mother, Jamie realizes a skewed perception of her father’s indifference and her own fears have led her to be harder on Alan than he deserves.
Forced to come to terms with her unresolved grief, Megan discovers the need to make amends and start fresh.
