Jennifer Garner Believes She & Ben Affleck Could Save Their Marriage

If Jennifer Garner gets her way, she and Ben Affleck will still be able to save their marriage.

"Jen really thinks there is a chance they can fix their relationship," an insider told RadarOnline.com.

The only problem is that Affleck doesn't share Garner's optimism or desire in the matter. "He wants nothing to do with getting back together," said the insider.

However, "Ben's being good and not going out in public much these days, so she has this glimmer of hope they can make it work."

Adding to Garner's confusion, the couple has been spending time together, including during a recently reported getaway to Big Sky, Montana with their children, Violet, Seraphina and Samuel.

Still, said the insider, nobody close to Affleck truly believes the couple, both 43, will ever fully reconcile their differences, which all came to a head when Affleck was reportedly getting close to his kids' former nanny, Christine Ouzounian, 28, a charge Affleck has vehemently denied.

"Their family time overshadows the relationship drama and somehow it's working on the surface but that's it," pointed out the insider.
