Regarding rumors of his infidelities, his wife said:“I live with this man. I see the down part. I see the sad part. I see every part. He has and knows he has that stability in me as his wife. That’s gives him strength, regardless of if he misuses it. I can’t dwell on that. But I do know that gives him a great platform to go and fly."

Doesn't sound to me like he is the pillar of virtue.

I'm not saying he's a bad guy. I am adding context to your line about the marriage lasting so long in Hollywood, and this context highlights that no one should be judged on one or even a few instances of their lives. Ideally we should all have the humility to know that to some extent we all live in the proverbial glass houses and that we all make lots of mistakes in our lives.
