Yes, But!... The Supreme Court's specific holding, which is the definitive statement on the issue, is NOT that the constitution protects choices to marry but rather than the the "constitution protects 'choices about marriage.'" The choice to enter into the intimate and expressive association of marriage is a "choice about marriage." Also, the choice to exit from the intimate and expressive association of marriage is a "choice about marriage." Choices to divorce are most certainly "choices about marriage."
