Garner and Affleck have both spoken in interviews about how they work together to parent their kids and how important it is that they’re on the same page. “I’m very grateful and respectful of her,” Affleck told People in February 2020. “Our marriage didn’t work, and that’s difficult. Both of us really believe that it’s important for kids to see their parents respect one another and get along, whether they’re together or not.” He continued, “My parents got divorced when I was young and I know how painful that is, and I knew that they [my kids] would have to go through that publicly. But kids are resilient. They appreciate the truth.” Garner was interviewed by The Hollywood Reporter in March, and was asked about a comment she made in a Vanity Fair interview in 2016. At that time, Garner said she knew she would no longer get to dance with her children’s father at their weddings. But now, she realizes she was wrong and that her relationship with Affleck means they can still have a good time together at milestone events. “When our kids get married, we’ll dance, I know that now,” she told The Hollywood Reporter. “We’ll boogaloo and have a great time. I don’t worry about that anymore.” For more celebrity news delivered right to your inbox, sign up for our daily newsletter.
