Monogamy
Relationship typeBeing romantically and sexually involved with one partner at a time.

Monogamy is the relationship structure where two people are exclusively committed to each other. It remains the default assumption in most dating contexts, though increasingly people specify it explicitly because non-monogamy has become more visible.
