According to an insider, Affleck, 42, opted to spend the holiday with his brother, Casey, and his own mom. Meanwhile, Garner's mother and father flew to L.A. From West Virginia to spend the day with her and her kids.
But it was hardly a happy occasion. Garner, 43, used the meeting to break the news that she and Affleck are separated, the source claims.
As Radar has reported, she is spending the summer filming Nine Lives in Montreal, while Affleck lives in L.A. And sneaks out for quick trips to Vegas for poker nights — as he did on May 3 and May 14.
Insiders tell Radar the couple are already warring over their kids, Violet, 9, Seraphina, 6, and Sam, 3, and that Garner plans to go for full custody in the event of a divorce, which could be announced before the couple's wedding anniversary on June 29.
Said one insider, "They're through. …He's told Jen that he wants the official statement to come out before their ten-year wedding anniversary."
