Josh Duggar is ready to move on.

The 28-year-old former reality star has left rehab after more than six months in a faith-based treatment center. Sources confirm to ET that Josh "has been out for a few days," though his current post-rehab whereabouts are not clear.

The eldest son of Jim Bob and Michelle Duggar and star of TLC's 19 Kids and Counting entered a long-term treatment center in August 2015, just after an Ashley Madison data breach led to his admission of cheating on his wife, Anna Duggar.

In a shocking statement released to the media, Josh also confessed to battling a "secret addiction" to Internet pornography. The revelation came to light just a few months after Josh admitted to molesting five minor girls, including four of his sisters, when he was a teenager.

"Anna is planning on getting back together with Josh, that's just how it goes," a source close to the Duggar family told ET last year. "The family was taught to have a new level of forgiveness towards Josh."

In January 2016, Anna revealed that she had only recently traveled to Josh's treatment center to visit with her husband and the father of her four young children.

"It was an important step on a long difficult road," Anna wrote on the family's official blog, thanking fans for their support during a difficult time. "I can never express how your kindness and prayers have brought encouragement when I needed it most -- outpacing the grief and discouragement at every turn. I trust that God will continue to show His love and tenderness toward us and bring beauty from ashes -- somehow -- as only He can do. Please continue to pray for me, Josh and our children."
