My wife confessed to two affairs after being caught in the latest. The first was 20 years prior. I found it hard to believe that there were no other affairs in between so she agreed to take a polygraph. She passed the test, but when I looked at her google search history the only topic she searched for prior to the test was “how to beat a lie detector test.” This has obviously made me feel like she had something else to hide. I have confronted her explanation just doesn’t make sense to me. What should I do? Another polygraph test?
