"Anna will not leave him," says the source. "As with her in-laws, she is turning more to her faith than ever. She and Josh are probably praying around the clock right now, I would assume."
Amid reports Josh had signed up with Ashley Madison, a website that specializes in facilitating extramarital affairs, Josh and his parents Jim Bob and Michelle Duggar broke their silence with a statement on the Duggar family website on Thursday, in which Josh says he has been "the biggest hypocrite ever" and confesses to a secret pornography addiction, as well as being unfaithful to his wife.
The source says that from their knowledge of Josh and Anna and the Duggar family, "no way is she leaving him" – adding that it would not come as a surprise if "on some level" Anna tries to "absorb some of the blame."
"Maybe not publicly, ever, but privately, there will be some suggestion of whether or not she should have been more aware of the pressures Josh was under, of the issues he was facing, and how she could have better counseled him or helped him," says the source.
"She is fully and permanently committed to her marriage and her children. And she'll have the support of Jim Bob and Michelle and everyone else in their circle in terms of staying with him and making this work," continues the source. "Divorce is not even something that will be discussed."

"As for Josh, in this moment, I would assume he feels like his life is ruined," says the source. "It will be such a steep and practically impossible climb to come back from this."
Josh and Anna, both 27, married in 2008 and have four children together: daughter Mackynzie, 5, sons Michael, 4, and Marcus, 2, as well as newborn daughter Meredith Grace, 1 month.
According to the source, in the end, "Josh and Anna will pull through this," and the scandal will be "seen as a test" for which the couple, Jim Bob and Michelle "will be determined not to fail."
