John Miller has no qualms with Jennifer Garner after her ex-husband Ben Affleck spending a ton of time at her place.

A source spilled to Life & Style magazine, “John has shown incredible patience and that he’s really endeared him to Jennifer.”

“Ben got a key to come and go as he pleases, and he’s been spending a ton of time at [Garner’s] place, coming over for dinners and hanging with the kids,” shared an insider.

The source told the outlet, It’s great for Ben’s state of mind and the kids love having him around.”

“John is very clear he’s not looking to force Ben out of Jen’s life, but the 24/7 nature of their relationship is just becoming way too much,” explained an insider.

The source mentioned, “Whenever they’re together, Ben’s blowing her up with random questions. And now they’re doing this movie together, it’s really got him questioning where he stands.”

OK! reported that Ben and Jennifer are currently working on an upcoming movie, Animals, together.

However, the source pointed out, “Jen has assured John and everyone else that she’s still all in, but you can’t blame the guy for wanting some actions to back up her words.”

Meanwhile, Ben fell back on Jennifer after his split from JLo, who filed for divorce on August 20.
