By November 2018, the couple were seen together in public at a Los Angeles performance of Dear Evan Hansen.

Jennifer Garner and John Miller Relationship Timeline
2018: First linked, and two divorces finalised
Garner and Ben Affleck separated in 2015. Their divorce was finalised in 2018.
Miller and Caroline Campbell married in April 2005. They share two children, Violet and Quest.
Their marriage went through a long process:
- Miller filed for divorce in 2011.
- The couple reconciled in 2012.
- Miller filed again in 2014.
- Their divorce was finalised in November 2018.
Garner and Miller were first linked in October 2018, around the time both divorces were reaching their end.
Garner has three children with Affleck: Violet, Seraphina, and Samuel.
2020: Reported split
In August 2020, reports said Garner and Miller had split.
Us Weekly reported that the split was amicable. A source told the outlet that Miller was ready for marriage and Garner could not commit at that time.
The couple did not announce the split themselves. So the exact date of the break is best described as reported, not announced.
2021: Reconciliation
In May 2021, Us Weekly reported that Garner and Miller were back together.
A source told the outlet, “Jen and John are back on. It started up a few weeks ago.”
They were photographed together again in New York City in August 2021.
2022 to 2026: Private, and still being spotted together
After 2021, the couple stayed out of the spotlight for long stretches.
They were still being photographed together in 2025, including a rare public outing in Los Angeles in February 2025.
In August 2026, they were reported together again on a date night in Los Angeles. That was described as their first joint sighting of 2026.
No split has been announced since the 2021 reconciliation.
Are Jennifer Garner and John Miller Engaged?
No. Neither Garner nor Miller has confirmed an engagement.
Engagement rumours have come up more than once. In December 2024, Garner was photographed wearing a diamond ring on her left hand while driving.
Neither Garner nor Miller commented on that sighting. A ring in a photo is not an engagement announcement.
The same point applies to later ring sightings in 2025 and 2026. Until either of them confirms it, the correct answer is: reported rumour only, not confirmed.
Are Jennifer Garner and John Miller Married?
No marriage has been announced.
Garner has spoken in the past about not rushing into marriage again. In a 2021 interview with People, she said marriage was not a priority for her at that time.
That does not prove what she thinks now. It does explain why rumours should not be treated as fact.
What About John Miller’s Ex-Wife?
John Miller’s ex-wife is Caroline Campbell, a concert violinist.
They are not still married. Their divorce was finalised in November 2018.
Campbell has performed as a soloist with major orchestras, including the Cleveland Orchestra, the Los Angeles Philharmonic, and the Boston Pops.
