Ben Affleck and Lindsay Shookus split after a year of dating

Ben Affleck and Lindsay Shookus have broken up after over a year of dating, ET has learned.

“They really tried to make it work and they just couldn’t right now,” the source says. “Their families came first, but ultimately having a bi-coastal relationship was difficult. They’re amicable.”

The news comes after the 46-year-old actor has been snapped two times with 22-year-old Playboy model Shauna Sexton, sparking romance rumors. On Sunday, the two were all smiles going through a Jack In the Box drive-thru in Los Angeles, and last Thursday night, they were photographed leaving Nobu Malibu together.
