When it comes to family and her relationship with Ben Affleck, Jennifer Garner only sees one solution. The "Nine Lives" actress has been separated from her famous ex for more than a year, but the pair still consider themselves a unit for the sake of their three kids.

"It has to be. You don't have a choice. It has to be," she said during a Thursday morning interview on the "Today" show. "We are definitely a modern family. We're doing really well."

The former couple recently spent a lot of time together in Europe.

"Ben was working in London on 'Justice League,' and I thought, 'Well, the kids should have that experience,'" Garner said of the family's travels. "He and I are great friends, and we just all went en masse."

The pair announced their separation in June 2015, one day after their 10th wedding anniversary.

A source previously told ET that the spouses are "making it work" and have yet to officially file for divorce.

Last February, Garner opened up to Vanity Fair in a tell-all interview, talking about her marriage to Affleck.

"I didn't marry the big fat movie star; I married him," she said at the time. "And I would go back and remake that decision. He's the love of my life. What am I going to do about that?"
