Jennifer Garner and John Miller seem to be putting down some major ground rules as their marriage approaches.

A well-placed insider shared news of this during their interview with Closer magazine.

Per their findings, Miller seems to have banned Affleck, and claim “John’s pleased his previous ultimatum worked and Ben’s not stinking up their romance with his clinginess, but he’s taking his hardline tactic a step further by insisting Ben be banned from the wedding.”

Reason being he thinks, “it would attract too much attention and be a nightmare, or so John thinks.”

However, “Jen’s tried to say Ben’s like a brother but so far John’s not budging.”

Still “Jen and John have gone ahead and started planning and want the wedding sooner rather than later with family and friends but no Ben if John has his way – and he might just have it.”

Overall, “there’s no doubt this won’t sit well with Ben, who’s been forced to sacrifice a lot for this guy already,” the insider also added before signing off.
