And the 'Jolene' hitmaker insists it's worked perfectly for the couple.
She told 'Entertainment Tonight' "I've always respected and appreciated that in him and I've always tried to keep him out of the limelight as much as I can.
"He said, 'I didn't choose this world, I chose you, and you chose that world. But we can keep our lives separate and together.' And we do and we have. We've been together 56 years, married 54."
Dolly actually thinks that not being "in each other's faces" has helped their relationship.
She said "Our joke about the fact, when people ask me why it's lasted this long, I say, 'Because I stay gone.' And there's a lot of truth in that - the fact that we're not in each other's faces all the time.
"But we do have a great respect and admiration for each other. We both have a great sense of humour. So, we have a lot of fun."
Asked how they spend their time when they're together, Dolly explained: "We have very similar tastes ... we love to travel around our little RV, and we don't like parties and all that stuff."
