Jennifer Garner’s romance with John Miller is going strong after a brief break. The pair began dating in 2018, the same year Garner finalized her divorce from ex-husband Ben Affleck.

Her priority is her children, that’s it. She’s focused on that. She’s remarkable.”

He added that the pair were a perfect match that September. “Jen is great. I talked to her for an hour today. She’s doing really well. She’s really happy,” he told Us at the time.

Garner's three children are going to see a lot more of Miller's two daughters, whom he shares with ex-wife Campbell. "They are spending a lot more time together," the source revealed.

October 2021

An insider told Us that friends of the couple think an engagement could be coming in the near future. "Jen and John are serious," the source said. "They are totally set on a long-term future together. They’ve taken their time to get this committed." 

Miller's life outside of Hollywood has also been a major bonus for Garner, the insider added. "It’s hard to remember Jen being this happy, and she definitely feels safe and secure with John, who’s unlike anyone else she’s ever dated," the source explained. "He’s hugely successful in his own right, of course, and she loves his mature and measured take on life. Being with someone as down-to-earth and calm as John is exactly what Jen needed in a partner.”

“Jennifer adores John and still sees a long-term future with him,” a source exclusively told Us, adding, “She’s just decided after a lot of thought that she’s just not in a hurry to rush down the aisle just yet and that she feels perfectly happy cherishing and enjoying what they have — for now — without a formal label.”

November 2023

“Jen and John are in a great place,” a source exclusively told Us after the pair celebrated Thanksgiving together. “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.”

A second insider noted that the duo have “a really special relationship” and that Garner “really enjoys” dating a non-celebrity following her public romance with Affleck. “For all his success in business, John is very down-to-earth,” the first source added. “Part of John’s appeal to Jen is how humble he is — this is a guy who wouldn’t know how to sound egotistical even if he tried.”

The first source went on to reveal that Miller has been “happy to go with the flow and do things Jen’s way from day one,” and often surprises her with romantic trips and date nights. “John is a romantic who’s big on making sweet gestures and spoiling Jen when she least expects it,” the source continued.

According to the first source, Garner and Miller’s inner circles suspect the pair will eventually walk down the aisle. “Jen and John want to take their time to plan out the specifics as far as the type of ceremony they want, where to live and whether or not they’ll need a prenup,” the insider told Us. “All that will come, but on their own timetable.”
