No one can say with 100% certainty that a couple is heading for disaster.
But social scientists have gotten pretty good at predicting who's most likely to wind up there. These couples share certain commonalities — in the way they fight and the way they describe their relationship, but also in their education level and employment status.
Below, Business Insider has rounded up seven factors that predict divorce.

Not finishing high school
It doesn't seem fair that couples who spend more time in school are less likely to get divorced. But that's what the research suggests.
A post on the Bureau of Labor Statistics website highlights a result from the National Longitudinal Survey of Youth (1979), which looked at the marriage and divorce patterns of a group of young baby boomers. The post reads:

Weathering daily stress
Don't underestimate the toll that stress can take on a marriage.
A 2007 paper, published in the Journal of Social and Personal Relationships, looked at the factors that led to divorce in European couples and found that daily stress was an important reason behind the decision to divorce in many couples.
Seemingly trivial experiences like forgetting an appointment or missing the bus turned out to create tension between spouses.
The authors even found that "participants reported the accumulation of everyday stress as a more relevant divorce trigger than falling in love with another person, partner violence, or even a specific major life event that would have instigated changes in their private life."
Withdrawing during conflict
When your partner tries to talk to you about something tough, do you shut down? If so (or if your partner is guilty of that behavior), that's not a great sign.
