A committed relationship is an interpersonal relationship based upon a mutually agreed-upon commitment to one another involving exclusivity, love, trust, honesty, openness, or some other agreed-upon behavior. Forms of committed relationships are: close friendship, courtship, long-term relationships (LTR), engagement, marriage, and civil unions. The term is most commonly used with informal relationships, such as "going steady," but may encompass any relationship where an expressed commitment is involved.
