The main idea is how the way couples form and manage their relationship can influence how stable it is over time. Living together before a formal commitment has been linked to higher odds of breakup later on, so it’s viewed as a risk factor for relationship instability. This pattern can arise from a mix of reasons: some couples who cohabit may start with more tentative commitment or different expectations about marriage, and the transition to a formal, official commitment can change the dynamics or reveal incompatibilities. There can also be selection effects, where people who choose to cohabit differ in ways that relate to dissolution risk.

In contrast, sharing finances is a practical arrangement that often accompanies deeper trust and planning, but by itself isn’t a predictor of instability. Marital satisfaction and effective communication are generally protective—higher satisfaction and better communication tend to make a relationship more stable.
