Last month, Ben Affleck was seen hugging Jennifer Garner at their son Samuel’s paintball birthday party. The intimate footage of the former couple sparked rumors of a reunion. And according to a source close to both, Jennifer’s current boyfriend John Miller, despite being a tolerant person, was uncomfortable seeing her with her ex-husband like that.

“Anyone can be affected, but this is nothing new,” the source said. “Ben and Jen have a unique relationship, especially since they were a couple.

According to reports, after the images of Ben and Jen went viral and talk of a reunion began to spread, John allegedly gave Jennifer an “ultimatum.” Despite having “supported Ben and Jen’s co-parenting relationship” since he began dating the actress, John felt the Gone Girl star “crossed the line” in the video, according to Page Six.

“John knows nothing is going on between Jen and Ben, but he doesn’t think the photos are flattering and feels it’s disrespectful to their relationship,” an insider said of the photos of Affleck affectionately holding Garner’s waist.

A source told Page Six that Miller “gave Jen an ultimatum. He either doesn’t want to see anything like that again or he has no choice but to walk away.”

In February, it was reported that John Miller was uncomfortable with the close relationship between Garner and her ex. A source told Page Six that Miller was “not happy” about the amount of time the two exes were spending together. The insider explained that John Miller “knows that Ben and Jen have been leaning on each other more than ever lately and have a really close relationship.”

John Miller reportedly felt that “their growing relationship was getting a little too much with Ben spending all the holidays with them like Christmas and Thanksgiving.”

“It used to be just about the kids, but John felt it could be more than just about their co-parenting relationship,” the source said.

Ben Affleck has not spoken much about his divorce from Jennifer Lopez but has been photographed spending more time with his first wife Jennifer Garner in the months since their divorce. Garner is said to have played a key role in helping her ex-husband get over his split from Lopez, taking on the role of “marriage counselor” for the troubled couple, with some friends concerned that she was forced to “play the mediator”.
