marital status of someone who lives in marriage

Tick "single." "Married", as it says here, "is the marital status of someone who lives in marriage", and we're just shacked up together.
Marca "soltero". "Casado", como dice aquí, "es el estado civil de alguien que vive en matrimonio", y nosotros solo estamos arrejuntados.
