A more thorough explanation:

Definition: A meretricious relationship is a stable, long-term relationship in which two people live together as if they were married, but without actually being legally married. This type of relationship is often considered archaic and outdated.

Example: John and Jane have been living together for 10 years, sharing a home, finances, and responsibilities as if they were married. However, they have never gone through the legal process of getting married. Their relationship is considered meretricious.

Explanation: In a meretricious relationship, the couple lives together and shares a life as if they were married, but they have not gone through the legal process of getting married. This type of relationship is often seen as less stable and less committed than a legal marriage, as there is no legal obligation to stay together.
