Anna Duggar and husband Josh Duggar are working on their marriage. The pair, who wed in 2008 and have four kids, had a difficult year during which Josh revealed he had a pornography addiction and had been unfaithful to his wife.

In a statement posted to the Duggar family website Friday, Anna and Josh revealed they were seeking marriage counseling to help them get their relationship back on track. “As we enter into a long family weekend together, we want to thank each of you for the prayers, love and encouragement you’ve sent our way,” the statement read. “Since the residential treatment program ended, we have been working with a professional marriage and family counselor to take important steps toward healing.”

The couple admitted it’s been difficult and said it’s going to take some time before they can rebuild trust and have a “truly healthy relationship” again. “We are very thankful for God’s forgiveness, grace and help, as it is our strength and guide to rebuilding our lives,” they said in the statement.” As the future unfolds, we are taking one day at a time and we are grateful for your continued prayers for both of us and our sweet children.”

During a recent episode of the TLC show “Jill & Jessa: Counting On,” which follows newlyweds and new parents Jill Dillard and her sister Jessa Seewald, Anna dished on her and Josh’s relationship saying that it was going to take “a lot of work” to get back on track.  

“There kind of is a long process ahead, but we’ll take it one day at a time and keep trusting God and do the right thing,” she said. “There’s a lot of little steps before it’s where it needs to be.”

As previously reported, Josh entered a faith-based rehab facility in Rockford, Illinois, in August shortly after his cheating scandal broke. His confession that he was unfaithful to his wife came months after news broke he had molested five underage girls when he was a teenager. It was later revealed that two of the girls were his sisters, Jill and Jessa.

On an episode last month of “Jill & Jessa: Counting On,” Jessa revealed her brother’s scandal helped bring her and husband Ben Seewald closer. “[It] strengthened our resolve to be true to our wedding vows,” she explained. “We cried a lot of tears. I felt like it was especially difficult for me because I had spoken out in defense of Josh and had stood up for him, and then there was a whole another wave of things that came through.”
