Denise Richards is reflecting on her tumultuous relationship with her ex-husband Charlie Sheen. 

Richards, 52, admitted she was "very naive" about Sheen’s, 58, battle with addiction when they first met. 

"I was ignorant when we got together about addiction because I was uneducated about addiction," she said on the "Just B" podcast. "That’s why I never thought he would ever relapse."

"This is not an easy road… I’ve been through hell and back with him," Richards added. 

Once Sheen "spiraled" into his addiction, the "Scary Movie 3" actress noticed that he was "no longer" the person she married and not sober.

"He was very different from what the public saw when he spiraled… after ‘Two and a Half Men’ when he was fired."

Despite their ups and downs, the "Real Housewives of Beverly Hills" alum confessed she "absolutely" does not regret marrying him and believed they came into each other’s lives to have their daughters.
