The father of four checked into a faith-based rehab facility in Rockford, Illinois, in August 2015 following a series of scandals, including his public confession to being addicted to pornography and having been unfaithful to Anna. The couple went on to celebrate their eight-year wedding anniversary in September. “Happy Anniversary, Josh and Anna,” the Duggar family wrote alongside a photo of the two on Facebook. “We are so thankful for God’s redemptive love in your lives.”
