Josh Duggar reportedly wasn't forgotten at Christmas time although he's seeking treatment at a faith-based rehabilitation center in Illinois for having cheated on his wife and developed an addiction to pornography.

According to a source, Josh's wife Anna Duggar and his family flew to visit him in rehab earlier this week, People reported.

"Everyone just had fun and seemed to be high spirits, including Anna," the source told People

A private plane owned by the Duggars reportedly departed Rockford, IL, Tuesday night and landed in Arkansas just after 10PM. An insider also said Anna and her youngest daughter, Meredith Grace, paid a visit to Josh one month ago via the same aircraft.

It remains uncertain how long Josh, 27, will remain at Reformers Unanimous for his "long journey toward wholeness and recovery."

Anna confessed in one part of the Jill & Jessa: Counting On special that Josh's scandal has been like "a bad dream." She was "hurt" and "shocked" to discover in August Josh had cheated on her and became obsessed with porn.

After all, the mother of four had enough to handle when Josh's "teenage mistakes" -- molesting a handful of girls, including his own sisters Jill Duggar and Jessa Duggar -- came back to haunt them via national headlines in May. Anna had learned of Josh's past before they wed in 2008, but it was still extremely difficult to deal with the public's backlash.

Despite all the emotional trauma, Anna has no intention to leave Josh and divorce him.

"When your world is shattered, there are a lot of emotions that you have to walk through. I think initially it was just crying and crying and crying, and then you get to the place where you can't cry anymore and then you get up and you start to go on with life, and then you start crying all over again," Anna said during the TLC special.

"I know there are those that feel I have every right to walk away from this marriage, and I respect other people's views. But in my heart, when I got married, I vowed to God first and then to Joshua for better or for worse, till death do we part."
