Ben Affleck ruining his marriage?

OHMYGOSSIP — Ben Affleck and Jennifer Garner‘s marriage is on the rocks, according to a new report. The pair — who raise three children together — have apparently hit a rough patch because they have spent little time together recently, thanks in part to the growing success of Ben’s latest flick, Argo.

“Ben really wants to win an Oscar for this film, and he’s become pretty obsessive about it,” says an insider.

“With Ben on the road promoting his movie, he and Jen are spending a lot of nights apart. They’re at a breaking point right now.”

“While Jen is trying to be supportive, friends say they aren’t sure how much longer she’ll be able – or willing – to juggle the kids and her career without Ben’s help. Is he does win that Oscar, he’d better thank Jen first!”
