Despite the fact that Ben Affleck's rehab facility, The Canyon, is more glamorous than the average vacation resort — yoga, a pool, and world-renowned chef included — the father-of-three is dead serious about his recovery. Even more than his health and career, Ben is terrified that his ex Jennifer Garner will forbid him from seeing their children if he continues down a reckless path of out-of-control drinking. "He knows that he still has a long way to go on his road to recovery but is looking forward to a fresh start once he's out," an insider revealed to Life & Style, adding that the actor will be at The Canyon for an "extended" period of time. "Ben is 100 percent committed. He promised Jen that once he's out of rehab, he'll be a changed man." As to whether she believes him remains to be seen, but Jen is clearly in full support of his sobriety.
