Matt Damon gave his thoughtful two cents on marriage when Entertainment Tonight asked how his childhood friend Ben Affleck is doing in the wake of his split from Jennifer Garner.Matt said, "I think marriage is insane. Like, it's a crazy idea, but I love being married to my wife, you know what I mean? So I wouldn't tell anybody else anything about their relationship." The actor sweetly gushed about his other half, saying, "I'm lucky I found my wife. And I guess, maybe, if there's any secret, it's that: it's to feel lucky."
