Ask two people why their marriage ended, and you might hear two different stories. One remembers the affair. The other remembers years of barely talking. Even when there’s a clear turning point, what happened before it can help explain why the marriage ended.
In a study published in the Journal of Family Psychology, researchers interviewed 52 divorced people who had taken part in a premarital education program. The most frequently cited reasons were a lack of commitment, infidelity, and frequent conflict. A separate study found that people also pointed to incompatibility and growing apart. Here’s how those and other commonly reported reasons can show up in everyday life. PMC
One or both partners stop investing in the marriage.
A lack of commitment can show up in small ways. One person keeps asking for time together, brings up problems, and follows up on promises to make changes. The other agrees in the moment but rarely takes the initiative. Some weeks, one spouse has more to give than the other. Over time, though, the person who keeps starting those conversations may decide they’re tired of being the only one who brings them up.
An affair breaks trust.
Discovering an affair can change how someone looks back on ordinary moments. A late night at work or a weekend away may suddenly raise questions. What happened? How long did it go on? Is there more to the story? For some people, the affair ends the marriage. In the study of 52 divorced adults, infidelity was also among the most frequently named events that pushed an already struggling marriage toward divorce. PMC

The same arguments keep coming back.
Some couples can predict exactly how a fight will go before either person finishes the first sentence. A conversation about chores turns into a list of everything one person did wrong last week. One spouse walks away, and the other brings it up again the next morning. Eventually, even a simple question like “Did you take out the trash?” can feel loaded because both people remember how the last conversation ended.
Money becomes a source of tension.
Money trouble can begin with a lost job, an unexpected bill, or a budget that leaves little room for emergencies. It can also come from different ideas about what money is for. One spouse might want to build up savings while the other feels responsible for helping family. If one partner starts hiding debt or making large purchases without a conversation, the next bank statement can raise questions about honesty and affordability.
They want different futures.
Two people may love each other and still disagree about whether to have children, where to live, or how much time to devote to work. Some of these choices feel distant when a couple gets married. They become more urgent when a job offer comes in from another city or one spouse realizes they’ve changed their mind about parenthood. Some decisions are hard to share because there’s no halfway option both people can live with.
They gradually grow apart.
At first, there’s a good reason to postpone dinner together. Someone has a deadline, a child has practice, or both people are exhausted. Months later, most conversations are about pickups, bills, and whose turn it is to buy groceries. The household may run smoothly while the spouses feel less involved in each other’s lives. In one study, growing apart was among the reasons people commonly gave for their divorce. Paul R. Amato, Denise Previti, 2003
Substance use disrupts daily life.
Some people in both studies cited drinking or drug use as a factor in their divorce. At home, the strain can show up in missed commitments, money the household was counting on, or one spouse repeatedly rearranging plans. A partner may spend more and more time covering responsibilities that used to be shared, from picking up the children to explaining another last-minute cancellation. PMC
Abuse makes staying unsafe.
Threats, physical violence, and controlling behavior can shape even ordinary choices, from who someone calls to whether they can leave the house freely. Domestic violence was among the most commonly reported final turning points in the study of 52 divorced adults. For someone living with abuse, the decision to leave can come down to protecting their safety and regaining control over their daily life. PMC
