Willie Robertson and Korie Robertson met at summer camp when they were just kids. Although they attended different schools, they would run into each other at youth group throughout the year and ended up tying the knot after graduating high school.

In January, the longtime loves celebrated 33 years of marriage. During their years together, they’ve welcomed three biological kids and adopted three children, all of whom are adults now. Through it all, they’ve managed to keep their relationship strong, and Korie opened up to Swooon about their secret to making it work.
