Jennifer Garner has been spending more time with Ben Affleck since his divorce from Jennifer Lopez.

And while that may be a good thing for the three kids the former couple share, there is someone who is uncomfortable with the bond between the Alias star and Argo director, both 52.

John Miller, Jennifer’s long time boyfriend, is reportedly uneasy with how much time the parents of Violet, 19, Finn, 16, and Samuel, 12, have been spending together. 

Miller ‘knows Ben and Jen have been leaning on each other more than ever lately and have a really close relationship,’ Page Six reported.

‘Their growing bond is getting to be a bit much when Ben spends all the holidays with them like Christmas and Thanksgiving,’ the insider said. ‘John feels like a third wheel.’

The outlet’s source said that Jen and Ben ‘text, call, and communicate far more than they have over the past several years.’

‘It used to be solely about the kids, but John feels like it could be more than just about their coparenting relationship,’ the insider says.

‘He doesn’t feel threatened in terms of Jen ever getting back with Ben, but at the same time it’s hard not to feel jealous when it’s clear they have a strong connection and friendship.’

Miller, 47, and the 13 Going on 30 actress have been dating on and off since 2018. 

‘Particularly since Ben’s divorce and with the LA fires and everything going on,’ the exes ‘have found themselves leaning on each other more than ever, ‘ Page Six reported.

Last week, it was revealed that Garner is pressuring Affleck to ‘grow up.’

‘Jen has a huge amount of sway with Ben these days, so she does feel quite obligated to police his behavior, particularly when it comes to the way he’s been treating JLo,’ In Touch reported.

‘He’s been so impatient with her and actually quite ungrateful, at least in Jen’s view.’ 

Jen and John have kept their relationship out of the spotlight.

Last month, Jen was spotted with a diamond ring on her left ring finger prompting speculation that she and John had gotten engaged.

Meanwhile, a source claimed in October that Jennifer and John are planning a wedding in Paris in the spring, where she allegedly went shopping for a bridal gown. 

‘Jen and John have taken a lot more trips to Europe than people realize. Paris is one of their favorite escapes and they’ve decided getting married there this coming spring is something they want to do,’ the insider dished.

The source also noted that a large ceremony in the French capital would be a marked contrast to when Jennifer and Ben eloped to Turks And Caicos in 2005.

‘This time around she wants a big wedding in a dream location and John is all for it. He loves the idea of giving her something that Ben never did, so he’s totally encouraging her to go all out. 

He’s got plenty of money and wants to totally spoil her,’ the insider shared with In Touch Weekly.

In December, another insider said Jennifer was ‘very happy with’ John and ‘spends a lot of time with him,’ seeing him ‘almost every day.’ 

Jennifer and Ben spent the day of Thanksgiving volunteering with their children, and then John spent the night at her house. Jen and Ben also spent Christmas together.

‘Jen truly just wants her kids to be happy. She will continue to make sure that they spend time together as a family and include Ben,’ People reported.

‘The kids enjoy when they all spend time together. Jen’s grateful that Ben’s doing well. They are friends, but that’s it,’ explained the insider.

Jennifer is said to have been a source of support for Ben amid the implosion of his marriage to Lopez.

An insider has said Ben regarded himself as ‘blessed’ to spend Thanksgiving with Jennifer Garner, with whom he feels he ‘can just be himself,’ via Page Six.

‘Even though Ben and Jen have been split for a while now, he feels a certain level of comfort with her,’ the source explained.

‘Ben has a strong relationship with Jen that will never dissipate because they have a lot of history together and she’s the mother of his kids.’
