Ben Affleck and Jennifer Garner‘s marriage has been “shaky”?

OHMYGOSSIP — Ben Affleck and Jennifer Garner‘s marriage has been “shaky” over the past few months. According to a new report from America’s Star magazine, Jennifer (42) joined Ben on his recent trip to Las Vegas because she doesn’t trust her husband of nine years when it comes to gambling.

When the actress returned to Los Angeles, she was seen leaving her psychiatrist’s office, leading friends to wonder if she was there to vent about her hunky hubby, Star reports.

“Jen and Ben’s marriage has been extremely shaky in recent months,” an insider reveals. “He’s constantly working, leaving her alone with the children for days and weeks at a time.”

Jen was with the actor when he was escorted out of a casino for counting cards on April 28, and although she didn’t make a scene in public, things got bad when the couple got back to the hotel room.

“She screamed at him, telling him he needed to quit gambling for good,” the source explains. “But he told her that he’s a grown man and will do what he wants.”

Jennifer also keeps an eye on Ben’s drinking and reputation as a ladies’ man, and resents that her career has taken a backseat while he continues to book jobs.

I wonder,…. who are these anonymous insiders who always have only the negative things to say?!
