Military families face pressures that can strain trust, communication, and emotional safety—especially across repeated deployments and long separations. In the past year, 49% of spouses reported loneliness during the service member’s absence, and 7.6% of married active-duty service members said their partner had been unfaithful. This page brings together military-specific and national evidence on relationship harm and betrayal, then explores the stresses and supports that can help families cope.
Key Takeaways
- 24% of active-duty military spouses reported having experienced intimate partner violence, indicating a significant prevalence of partner-related harm in this population
- 7.6% of married U.S. active-duty service members reported that their partner had been unfaithful (as defined by the study)
- 1 in 4 (25%) women in the U.S. military experienced sexual assault or rape (estimates vary by subgroup), underscoring exposure to forms of violence that can co-occur with relationship breakdown and misconduct
- A large military family survey reported that 49% of spouses experienced loneliness during the service member’s absence (risk context)
- A RAND study estimated that deployment-related stressors affect about 70% of military families to some degree (relationship strain context)
- RAND found that about 40% of service members reported that deployment increased stress on their families (mechanism for relationship strain)
- 8% of military family respondents reported that cheating/infidelity had occurred in their relationship in the prior year (survey measure reported in the study)
- In a study of military couples, 23% of respondents reported relationship betrayal behaviors (including infidelity items), indicating the importance of measurement design
- National data for intimate partner violence shows that 1 in 3 women experience violence by an intimate partner in their lifetime (a relationship-harm benchmark relevant to misconduct risk)
- Relate/relationship counseling participation: a meta-analysis reports that couples therapy produces a moderate improvement in relationship satisfaction (standardized mean difference about 0.35)
- CBT-based interventions for relationship distress can reduce symptoms with effect sizes around Hedges g ~0.50 in controlled studies (intervention effectiveness benchmark)
- SAMHSA reports that 47.3 million U.S. adults had any mental illness in 2023 (context for demand for behavioral health services)
- Cheating-themed keywords receive sustained search volume; a sample dataset (Google Trends) shows 'cheating' search interest index reaching values above 60/100 during certain months in the U.S.
- In a study of online infidelity forums, 71% of users reported seeking emotional support or validation rather than purely sexual gratification (indicates online behavioral patterns relevant to infidelity)
- Meta analysis shows that smartphone-based location-sharing and communication patterns can influence relationship satisfaction (digital monitoring context); reported effects indicate moderate association (r about 0.30 in pooled results)
Roughly 1 in 13 military spouses report infidelity in a year, amid widespread deployment and relationship strain.
