Almost daily, the news bears a story about sexual forays of "family values" activist and former reality TV star Josh Duggar. But standing silently by his side and gazing at him in adoration is his oft-forgotten wife, Anna.

On Wednesday, it was reported that Josh Duggar entered a treatment facility while on Tuesday, the couple was apparently hiding out with their small children in an Arkansas mountain home. It's unclear whether Anna has been left alone after news of her husband's infidelity broke.

Citing an unnamed source, People Magazine implies that divorce is unlikely, because Anna, whose maiden name is Keller, was raised by a Christian family "more extreme" than the Duggars. She is one of eight siblings.

"Anna and her siblings were always taught that if you follow these 10 steps or whatever, God would bless you," the source told People.

Anna reportedly met Josh at a homeschooling convention in 2006, when she was still a teenager. But her family structure was so stringent, she wouldn't have been allowed to gossip about her love interest with her siblings. The children were not allowed to talk about their feelings among themselves, People reports.

"They always got 15-minute, one-on-one sessions with their mom every week. That was the time to share their feelings, but other than that they had to keep their feelings to themselves," the source told the gossip magazine.

Once full of spunk, the source said Anna has become isolated and soft-spoken since marrying into the Duggar family.

In May, In Touch Weekly revealed Josh had molested five underage girls, including his sisters. This month, Gawker revealed he had two paid accounts with Ashley Madison, a website created for the purpose of infidelity. This week, porn actress Danica Dillon claimed Duggar had paid her for sex while Anna was pregnant.

The Duggar family had actively campaigned against LGBT rights while promoting the idea that the "traditional family values" they lived by were morally superior.

Anna's brother, Daniel Keller, has blasted Duggar and offered to go get his sister and let her stay with him with her children. She has not publicly responded to his offer.
