Jen & John IT'S OVER!

Six years into her romance with businessman John Miller, Jennifer Garner's happily ever after is foiled by needy ex Ben Affleck

- 

The outing marked a rare public moment of unguarded bliss. Dressed down in sweatpants and sneakers, Jennifer Garner and John Miller couldn't stop smiling as they traded laughs while holding hands during a casual weekend stroll along a tree-lined street in Santa Monica on April 27. Headlines proclaimed that the deeply private couple were "very much in love."

That sweet scene would be the last time Jen and John would be seen together. The pair, who've gone at least 110 days without being publicly photographed by each other's side, "have been on a break," a source confirms to Life & Style. And, according to the source, it's no coincidence that their six-year romance began to suffer around the same time Jen's ex-husband Ben Affleck began leaning on her this spring, as his marriage to Jennifer Lopez crumbled. "Jen's had so much going on with Ben, it just took a toll," explains the source, "and she and John ended up going their separate ways. It wasn't her choice."
