Once upon a time, Jennifer Lopez allegedly had a problem with Ben Affleck‘s relationship with ex-wife Jennifer Garner. And now it seems like the 13 Going on 30 actress’s long-term boyfriend might also have an issue with her friendship with the Gone Girl actor.

While Affleck and Garner are always going to be in each other’s lives due to the three children they share together – Violet, 18, Seraphina, 15, and Samuel, 12 – they apparently are spending even more time together now that Affleck is divorcing the JLo Beauty founder, if we are to believe insiders. And that is something that her long-term boyfriend isn’t too happy with!

Jennifer Garner’s Boyfriend Isn’t Happy With her ‘Unfathomable Support’ For Ben Affleck

According to reports, the Deadpool & Wolverine actress is lending her support to the Argo actor amid his divorce from the Shotgun Wedding actress – and that is unfortunately jeopardizing her relationship with long-term boyfriend John Miller.

“John is at the end of his rope with what he considers Jen’s ‘unfathomable’ support for her ex-hubby while ignoring him in the process,” an insider spilled to RadarOnline.

And Garner and Affleck’s constant communication isn’t just a problem for Miller, as the insider said that it was consistently a problem for the “I’m Real” singer too…

Jennifer Garner Is Reportedly Working Hard To ‘Salvage’ Her Relationship

“J-Lo was making a point that she was humiliated by Jen and Ben’s ridiculous closeness,” the source said, adding: “Don’t think John didn’t feel the same way. John is still incredulous that the woman he was close to marrying pushed him aside to focus on repairing her ex’s love life. How is he supposed to feel?”

The insider did indeed sense that an engagement was on the cards for Garner and Miller, who have been together since 2018; and the Elektra actress reportedly wants to make sure she doesn’t jeopardize their relationship.

According to the insider, she is now doing everything she can to make amends with her boyfriend of six years. “Garner realizes she may have overplayed her hand by putting John in second place in this dynamic. Now she’s trying to woo him back and salvage the relationship,” the source confirmed.
