What Are the 4 Causes of Divorce?

What Does Research Say About the Main Causes of Divorce?

A landmark study published in the Journal of Family Issues surveyed 886 divorcing individuals and identified distinct patterns in why marriages fail. The researchers found that lack of commitment was cited by 73% of participants as a major contributor—making it the most common cause by a significant margin.

The four primary causes break down as follows:

Cause	Percentage Citing as Major Factor
Lack of commitment	73%
Infidelity	55%
Too much conflict/arguing	56%
Growing apart/incompatibility	55%

How Does Lack of Commitment Lead to Divorce?

Lack of commitment manifests in several ways: prioritizing work or hobbies over the relationship, unwillingness to address problems, emotional withdrawal, or failing to invest in the marriage's future. Couples who report commitment issues often describe a gradual erosion rather than a single breaking point. This cause frequently underlies other problems—when one spouse stops being committed, they may also stop communicating effectively or working through conflicts.

Why Is Infidelity Such a Common Cause?

Infidelity was reported as a major contributor by 55% of divorcing individuals and served as the "final straw" more often than any other factor. The study found that 24% of participants named infidelity as the primary reason their marriage ended. Importantly, emotional affairs—not just physical relationships—can be equally devastating to marital trust.

What Role Does Conflict Play in Divorce?

Excessive arguing and unresolved conflict affect 56% of divorcing couples. However, research distinguishes between constructive conflict (which can strengthen relationships) and destructive conflict patterns including:

• Criticism and contempt
• Defensiveness and stonewalling
• Escalating arguments without resolution
• Inability to repair after disagreements

Dr. John Gottman's research identifies these "Four Horsemen" communication patterns as predictors of divorce with over 90% accuracy.

How Does Growing Apart Contribute to Divorce?

Incompatibility and growing apart (cited by 55% of couples) often develops gradually over years. Life transitions—having children, career changes, or simply maturing differently—can create distance. Couples who married young face higher divorce rates partly because significant personal development occurs in early adulthood.

Are There Differences Based on Who Files?

The NCBI study revealed an interesting pattern: participants were more likely to blame their partner than themselves for divorce-contributing behaviors. Women initiated approximately 69% of divorces, according to the American Sociological Association, and were more likely to cite domestic violence and substance abuse as factors.

What About Other Contributing Factors?

While the four primary causes dominate, additional factors frequently contribute:

• Financial problems (36% of couples)
• Substance abuse (34%)
• Domestic violence (23%)
• Health problems (18%)
• Lack of family support (17%)

Most divorces result from multiple overlapping causes rather than a single issue. Understanding these patterns can help couples identify warning signs early—though addressing serious marital problems typically requires working with a qualified family law attorney or marriage counselor.
