After I Do - Taylor Jenkins Reid - Simon and Schuster

When Lauren and Ryan’s marriage reaches the breaking point, they come up with an unconventional plan. They decide to take a year off in the hopes of finding a way to fall in love again. One year apart, and only one rule: they cannot contact each other. Aside from that, anything goes. Lauren embarks on a journey of self-discovery, quickly finding that her friends and family have their own ideas about the meaning of marriage. These influences, as well as her own healing process and the challenges of living apart from Ryan, begin to change Lauren’s ideas about monogamy and marriage.
