Heres the sad twisted tale...

I found out my wife was cheating on me. It took two weeks to get all the info on all her affairs. I still didnt believe her and was worried there was alot more. She said she was willing to take a lie detector test, so I called her on it. When I first met the polygraph tester I told him about my wife's history and he suggested a certain type of test. It was a sexual history test. She was to record every encounter intimate and sexual with other men since the time we were married on paper. He would then test her on what she wrote if it was truthful or not. She failed it. The only question she got right was her name. He asked only 6 questions to her and asked the same series of questions 3 times. The tester is certified and works for Internal affairs for the state I live in. Is she lieing or not?
