Matt Damon has allegedly distanced himself from Ben Affleck following his latest stint in rehab. It was recently revealed that Jennifer Garner convinced the father-of-three to head to a rehabilitation facility to seek treatment once again for alcohol addiction.

Ben has previously gone to rehab in 2001. In March 2017, he revealed he had completed treatment for alcohol addiction.

According to Radar Online, the Martian star, who has been friends with the Oscar winner since they were children, does not want to get involved in the 46-year-old Justice League actor's personal life. A source said: "Matt will always love Ben and thinks of him like a brother. Sometimes you have to step away to let people save themselves."

Damon is currently "focused on his wife and his family and his partying days are long, long behind him, but Ben is still living in the fast lane," the insider added.

The source shared that despite Damon and Affleck's growing distance, they "will always have each other's backs," but as of now, rehab is something he "is going to have to do all alone."

Damon and Affleck's bond is one of Hollywood's longest and most fascinating friendships. In 2015, during an interview with The Hollywood Reporter, the 47-year-old actor shared Affleck has been wrongly portrayed for his personal life choices. He also added that Affleck's low point in life was when he dated Jennifer Lopez - they dated for two years, but called off engagement in 2004.

"There's nobody who's more misunderstood," Damon said of Affleck. "Ten years ago, the public image of him could not have been farther apart from who he actually is. It was like he was being cast in a role, that he was a talentless kind of meathead, with his whole relationship with Jennifer Lopez."

He continued: "He just got cast as this person that he wasn't. It was just really painful. It was painful to be his friend, because it wasn't fair, you know? To my mind, nobody really got him at all. And through his work, he climbed from the bottom of the mountain all the way back up to the top and past where either of us had ever been."
