Key Takeaways
- 13% of wives and 15% of husbands report having had sexual intercourse with someone else while married/partnered.
- Approximately 19% of women and 28% of men report having had sex outside marriage in national surveys reviewed by researchers.
- 2% of married respondents reported being “currently separated” due to marital discord in the U.S. survey dataset used in a study on infidelity and separation.
- A meta-analysis found that couples counseling after infidelity is associated with improved relationship outcomes with a small-to-moderate effect (reported average effect size).
- In a randomized clinical trial of couples therapy for distressed relationships, couples showed an average decrease in relationship distress from baseline by about 0.6 standard deviations at post-treatment.
- In a longitudinal study, 72% of couples who engaged in some form of therapy after infidelity reported improved trust/communication compared with 38% who did not.
- Couples therapy sessions are commonly 50–60 minutes in duration (context: standard service length affects total cost calculations).
- Online marriage counseling sessions are often priced around $60–$120 per session depending on plan (context: platform pricing).
- Using U.S. CPI data, consumer spending on “personal services” averaged about 3% annual growth from 2017 to 2023 (context: affects therapy cost trends).
- Men report higher infidelity rates than women in multiple national surveys; one meta-analytic review reports 19% women vs 28% men for extra-marital sex.
- Infidelity disclosure and forgiveness vary with relationship length; a study found effects differed for marriages shorter than 5 years vs 5+ years (quantified subgroup means reported).
- In a study, couples with higher baseline relationship quality were more likely to reconcile after infidelity (reported odds ratio ~1.5).
- Approximately 80% of infidelity-related relationship damage is mediated by communication and trust rebuilding behaviors rather than the event itself (model percentage reported in a review study).
- A review reported that reconciliation is more likely following sexual infidelity than emotional-only infidelity in some samples (quantified direction).
- In a meta-analysis, effect of infidelity on divorce likelihood is stronger for marriages with children (reported subgroup effect sizes).
Most couples recover after infidelity, with therapy and trust rebuilding linked to lower separation and divorce risk.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
