Reality bites!

Ben Affleck spent the last few days having a romantic time with girlfriend Lindsay Shookus in NYC, but it was back to the grind today as he arrived at his rehab facility in West Hollywood. The actor has rededicated himself to a life of sobriety, and apparently it was Jen Garner that he turned to when he realized he was slipping back into old habits.

"Ben reached a breaking point. He knew he was spiraling and was unhappy. Ben told her everything that was going on with his life. He was devastated but knew he had to change," a source dished to Us Weekly.

Despite their divorce and his new relationship, the mother-of-three still supports the Oscar winner.

"After everything they’ve been through, she is going to continue to be there for him when he needs her. No matter what the circumstances. From the smoking to drinking and gambling, Jen has always been the person who can get through to him. She keeps Ben in line as much as she can," the source added.

Starting a new romance isn't the best idea when you're trying to work on yourself, just sayin!
