Jennifer Garner’s boyfriend John Miller ‘feels like a third wheel’ around her ex-husband Ben Affleck

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.
