Co-habitation refers to the arrangement where two individuals live together in a long-term relationship without being legally married. This living situation can occur among couples of various orientations and is often seen as a way to share expenses, responsibilities, and companionship. Many people choose co-habitation for various reasons, including financial benefits, personal preferences, or as a step before marriage. It can provide a way for partners to test their compatibility and strengthen their relationship while enjoying the comforts of shared living. Legal rights and responsibilities may vary depending on the jurisdiction and the couple's circumstances.
