committed

If you're committed to something, you're pledged or obligated to do it. If you’ve already jumped out of the plane, you’re committed to your skydive — there’s no turning back!

When you're committed to a partner as you are in a marriage or a domestic partnership, it means that you're associated with them exclusively and not with anyone else. Often during wedding ceremonies or vow renewals, you will hear the parties recite a phrase confirming that they are committed to each other, such as "I take you...to have and to hold...to love and to cherish, from this day forward, until death do us part."
