Ben Affleck and Shauna Sexton are no longer seeing each other, PEOPLE has learned.
“There was nothing to split from as it has been casual,” a friend of Affleck’s tells PEOPLE.
The end of the pair’s brief relationship comes just days after the two took a romantic vacation to Montana over the weekend, where Sexton, 22, posted a shot of Affleck, 46, on her social media for the first time.
“He enjoyed being with her but is working on himself, and being together with her at this time is not something that works,” the friend adds. “He will date in the future, but for now his focus is on his sobriety, family and his next project.”
The actor and the Playboy model first seen together at a cozy dinner at Nobu on Aug, 16, less than a week before Affleck checked into rehab seeking treatment for alcohol addiction on Aug. 22.
Days after Affleck checked into rehab, Sexton was seen driving the actor’s SUV and even visited him at the treatment centers during his stay. They were then seen together at his house shortly after he completed his treatment and went on vacation together later that week.
