'Feels like a third wheel': Jennifer Garner's boyfriend is unhappy with her growing relationship with Ben Affleck following his divorce from Jennifer Lopez

Page Six, citing its source, reports that 52-year-old Jennifer Garner's boyfriend, 47-year-old businessman John Miller, is extremely concerned about her growing relationship with her ex-husband Ben Affleck.

According to the publication, John noticed that Garner began communicating more often with 52-year-old Ben Affleck, and this began to worry him. “Lately, Ben and Jennifer are drawn to each other more than ever, they have a very close relationship. Their growing relationship is starting to cross the line, because Ben spends all the holidays with his ex-wife, including Christmas and Thanksgiving. John feels like a third wheel,” the insider said.

He added that Garner and Affleck have started texting and calling each other more often than they have in the last seven years, and if before they mainly discussed children, now John suspects that their relationship is built on more than just that: “He’s not afraid yet that Jennifer might go back to Ben, but at the same time it’s hard not to be jealous when such a strong connection and friendship is obvious.”

To complicate matters, Affleck recently divorced 55-year-old Jennifer Lopez, which has brought him even closer to his first wife. The devastating California wildfires that killed Garner's friend have added to the urgency for close contact.

Let's remember that Jennifer Garner and Ben Affleck were married for 10 years and are raising three children together: 19-year-old Violet, 16-year-old Seraphina, and 12-year-old Samuel. Garner started dating John Miller in 2018. It is noteworthy that Affleck trusts Garner so much that he even wanted her to find him a new girlfriend.
