Earlier that month, Affleck said he hoped he was “a pretty good dad” while on theTodayshow.

“I certainly try very hard,” he said. “I’m lucky they got a great mom, and she helps out a great deal with making sure that we co-parent in as good a way as possible. Dads are so important to kids,and it’s our responsibility to be therefor them — to be present, to be mindful, to be attentive, to be part of their lives, to be as in it as moms.”

“That’s really the central preoccupation in my life,” the actor admitted. “The focus of my life is what I love doing. It’s what makes me happy, and the rest of the stuff kind of follows.”

Affleck — whosedivorce from Garner, 47, was finalizedin November, three years after they separated — continued to praise Garner when hostHoda Kotbpointed out how much love he seems to still have for her.

“Of course, she’s wonderful,” Affleck responded. “When somebody is the mother of your kids, they’re gonna be the most important, central person in your life, and that’s good.”
