Jennifer Garner's boyfriend, John Miller, wasn't fond of the "cozy photos" of her and ex Ben Affleck that surfaced earlier this month.

An inside source recently told Page Six that Miller "has always been supportive of Ben and Jen’s co-parenting relationship but feels Ben crossed the line." The photos, captured last week when Garner and Affleck, who share children Violet, 19, Seraphina, 16, and Samuel, 13, were enjoying a paintball outing with their son, caused quite a stir among fans.

The flirty snaps showed the Argo star holding Garner's midsection, and she did not pull away. The source continued:

"John knows there’s nothing going on between Jen and Ben, but he doesn’t think those photos are a good look and feels it’s disrespectful to their relationship." The CaliGroup CEO had such a distaste for the pics that he allegedly gave the 13 Going on 30 actress an ultimatum stating that he "doesn’t want to see anything like that again or he has no choice but to walk away."

Romance rumors began to swirl when a source remarked on Affleck's desire for "another chance" with his ex despite poor timing.

"Ben knows it’s just not realistic at this time in their lives. Ben just got out of a marriage and finalized his divorce [from Jennifer Lopez], he is really busy with work and is focused on this new chapter plus, Ben respects Jen’s relationship with John [Miller] and would never come between them."

Another source assured Garner is happy with Miller and has no interest in reigniting a spark with Affleck.

"Jen has a great co-parenting relationship with Ben, and that’s where things stand on her end at the moment."

Affleck's most recent ex, Jennifer Lopez, whom he finalized a divorce with in February, was "furious" to see the flirty snaps of the Justice League star, referring to the sight as "salt in the wound," per Page Six.
