Ben Affleck and Jennifer Garner’s Boyfriend Share ‘Mutual Respect’

Jennifer Garner’s romance with boyfriend John Miller is going strong — and so is Miller’s relationship with Garner’s ex-husband, Ben Affleck.

“Ben is super down-to-earth, and so is John,” an insider exclusively reveals in the new issue of Us Weekly. “They have a mutual respect for each other and are always very friendly with one another.”

Garner and Affleck, both 51, called it quits in 2015 after 10 years of marriage. Affleck later moved on with Jennifer Lopez, whom he wed in July 2022. Garner, meanwhile, has been dating Miller since 2018.

The source adds the two couples “are all mature” and have worked hard to make “their children the focus of those relationships.”

Garner and Affleck share daughters Violet, 17, and Seraphina, 14, and son Samuel, 11, while Miller shares two kids with ex-wife Caroline Campbell. Lopez, 54, shares twins Max and Emme, 15, with ex-husband Marc Anthony.

As the group has worked together to blend their families, Affleck and Miller have developed “a lot of mutual admiration and respect,” a second source tells Us.

Lopez and Garner, meanwhile, have cultivated their own friendship since Lopez rekindled her romance with Affleck in 2021. “Over the past year or two, they’ve definitely become close and have gotten to know each other much better,” an insider told Us in May. “Both of them are incredible mothers and always put their children’s needs first.”

Garner and Miller have largely kept their romance out of the spotlight, but they’ve recently become less guarded about their relationship. Earlier this month, Garner was photographed blowing her boyfriend a kiss as they said goodbye outside her California home.

“Jen and John are in a great place,” a source tells Us in this week’s cover story. “They used to go out of their way to keep a low profile, but they’ve both become very secure with their relationship and how it’s all worked out.”
