Military spouse infidelity is often assumed to be driven by one factor, but the latest results suggest it shifts with age, separation patterns, and even where families live. A 2021 longitudinal DoD analysis found cheating linked to 45% of military divorces, and the percentages swing dramatically by demographic. Those contrasts raise a harder question than “how common” it is, namely who experiences the pressure most and when relationships unravel.
