Jennifer Garner and Ben Affleck have made their marriage last for over nine years, which is like a lifetime by Hollywood standards. So of course they are often asked how they make it work. And now Garner is telling us.

In an interview with InStyle magazine for their October issue, Garner says her marriage to Affleck comes down to a "bit of mindfulness." Adding that she doesn't need to be wined and dined all the time, but that

we're definitely in a very mindful place where we're making an effort to be together, do things at the same time, and be loving."

A statement that totally makes sense.

But her next statement may throw some for a loop.

Garner is apparently all about embracing parenthood along with Ben, but they divide things by what she calls the mom-dad line.

What she means by that as she explained to Jimmy Fallon when she visited The Tonight Show is that

If it has to do with making food, or [doing] homework or anything that has to do with actually functioning -- sorry it's true -- that's a mom thing. And then coming in just as you're getting them to bed and picking them up by their heels and swinging them around, that's a dad thing. Anything fun, that is Ben."

Maybe it's just me, but why can't fun stuff be a "mom" thing too? Do you think parents need to take on such specific roles to make things work? And what role do you see yourself in in your relationship?
