The Write Choice by Allie Samberts

Loving someone is seeing their worst moments and choosing them anyway.
When Katie and Brandon unexpectedly became parents, they were just starting to fall in love with their baby and each other. Life was good.
Now, seven years later, Brandon has a wife, two kids, and a career in New York City. He’s just having trouble figuring out how to balance it all.
Katie—eight years sober and immersed in motherhood—is frustrated with her husband’s late nights and her own loneliness. She’d love to fill the gaps with her art, but she doesn’t have much time.
Suddenly, Brandon is offered a golden opportunity: taking over his parents’ architecture firm. The catch? It’s in Chicago. But when Katie’s sobriety is put at risk, he makes a quick decision to transplant his family to suburban Leade Park, Illinois.
