Clearly it went well!

We caught Ben Affleck heading into a meeting this afternoon after returning to LA following his Montana getaway with girlfriend Shauna Sexton, and when we asked him about the trip, he couldn't help but crack a slight smile before waving us away. Hey, it's somethin'!

A lot of people assumed the Oscar winner and the Playboy model wouldn't last after he went to rehab, but it appears their romance is going strong.

A source tells X17:
    "Ben likes spending time with Shauna because she's young, upbeat, and uncomplicated. With Lindsay Shookus, there were so many big conversations about their future, and with Shauna, he can just relax and laugh. Contrary to ridiculous reports, he's not planning on "proposing" anytime soon, but he's enjoying getting to know her."

We're happy he's happy!
