Earlier a thread appeared in AskReddit titled "Redditors whose marriage lasted less than a year, what went wrong?" I immediately noticed a pattern of men who caught their wives fucking other men. So I meticulously read every single main story, and counted the results. Women were almost 3 x more likely to cause a divorce due to being caught cheating.

This was the conclusion: https://www.reddit.com/r/AskReddit/comments/5sah9t/redditors_whose_marriage_lasted_less_than_a_year/dde5akk/
