“It’s funny. I think when you’re an adult and you understand what mental health is and you know all of the things we have learned, as individuals, you always hear that marriage is work and it’s the best job you’ll ever have, but it requires effort,” Bush, 39, explains.

“And we got engaged and I looked around and said, ‘Why didn’t anyone tell me how sweet and pure this would be?’ It’s just so sweet and it’s a time that I’m very intentionally cherishing,” she adds. “And you know, more adventures on the horizon.”
