Designer relationships are based on egalitarianism and mutuality, not on proprietary thinking. From this perspective, if people decide they will have multiple partners, the approach is the antithesis of cheating. In the conventionally monogamous model, each party owns the other (a modern variation on the more antiquated view of woman as property). In designer relationships, each party voluntarily owes the other transparency, some measure of emotional loyalty, and a determination to abide by agreements.
