Jennifer Garner’s long-running romance with John Miller may be nearing a breaking point, at least according to new tabloid reports. Insiders claim the CaliBurger CEO is growing increasingly frustrated with what he sees as Garner’s lingering emotional closeness to her ex-husband, Ben Affleck—and that his patience may finally be wearing thin.
Sources cited by the National Enquirer allege that Miller is “ready to walk” if Garner doesn’t show a stronger commitment in the near future. The couple has been on and off since 2018, and after nearly seven years of navigating a complicated dynamic, Miller is reportedly questioning whether there’s room for him to truly come first.
The timing of the claims comes as public attention around Affleck has intensified following his split from Jennifer Lopez. That renewed spotlight has once again highlighted Affleck’s close co-parenting relationship with Garner, which insiders say has become a growing source of tension in her current relationship.
Garner, 53, shares three children with Affleck—Violet, 20, Fin, 16, and Samuel, 13—and the former spouses have long been praised for maintaining a warm, supportive relationship since finalizing their divorce in 2017. They’re frequently photographed together at school events, family outings, and milestone moments, projecting what many consider an ideal co-parenting partnership.
But sources close to Miller claim that dynamic has blurred emotional boundaries. While Miller reportedly respects Garner’s devotion to her children and understands that co-parenting comes first, insiders insist the issue isn’t about parenting—it’s about emotional priority. According to the report, Miller feels like he’s constantly playing second fiddle to Affleck rather than being treated as Garner’s long-term partner.
Those same sources say Miller has tried to be patient for years, but now believes the relationship with Garner often takes a backseat to her bond with her ex. Even though Garner has allegedly reassured him that boundaries have improved, insiders claim the pattern hasn’t truly changed.
The situation is said to have escalated privately, with Miller making his expectations known behind closed doors. While he reportedly hasn’t issued a formal ultimatum, sources allege he’s made it clear that if Garner can’t offer what he considers a “proper commitment” by 2026, he’s prepared to walk away.
Garner has consistently kept her relationship with Miller out of the spotlight, rarely speaking about him publicly. Her focus, she’s said in past interviews, remains on providing stability for her children. Miller, who maintains a low profile, has also stayed silent amid the latest rumors.
Neither Garner, Miller, nor Affleck has addressed the report, and their representatives have declined to comment, leaving the claims firmly in tabloid territory. Still, with emotions, blended family dynamics, and relentless public scrutiny in play, insiders suggest the relationship is at a crossroads—one that could soon force a difficult decision.
