The 50-year-old gold medalist said the separation was "very hard" and that it still felt 'very new'.
She went on about her split, "In my mind I was like, 'I lost, I am a failure, ' and that's just not the case. People don't know that", Retton told her pro dancing partner Sasha Farber. "I felt very alone".
The former couple Wednesday in 1990, but only finalized the divorce in February of this year. "It's the first time I've actually said it publicly", the retired gymnast said on camera.
Retton, who Wednesday Kelley in 1990, said they finalized their divorce in February, "so it's very new".
"Thank God for my four girls", she said. "We still love one another, but we weren't great together anymore".

Schumacher, with 91, also has more race victories, another target for Hamilton during the two remaining years of his current Mercedes contract.
The pair share four daughters: Shayla, 23, McKenna, 21, Skyla, 18, and Emma, 16.
She added that her daughters had helped her through the divorce.
"They love me unconditionally", Retton said.
During last week's Disney night episode, Retton revealed how she connected to the Mulan song, "Reflection", that she and Farber danced to. "I was ready, I was prepared, I gave it my all, and I was confident, I found that confident woman I was looking for when I started this process".
She smiled, saying, "I don't know, we'll see". "There's that mental switch".
