How long do boyfriends and girlfriends live together before they get married?

There is no timetable for this, but it depends on the development and mutual adaptation of the relationship between men and women after interaction. After general communication, especially after cohabitation, both of them feel happy and suitable for each other. Maybe they will get married in a few months soon, but after a few years, they may even feel inappropriate and break up. In short, everything goes with the flow. When their relationship develops to the point of getting married, naturally both of them want to get married.
