Yesterday my ex-boyfriend asked me if he could take a polygraph test as part of his effort to try to earn back my trust, specifically, to confirm that I'm aware of every affair he's had, and to prove to me that he didn't do two of the things I suspect him of. I didn't even know polygraphs to detect lies for the benefit of a relationship was a thing. I might be crazy for even considering it, but if there's any chance he's telling the truth and we could live happily again I'm willing to take it. So, I would like to know everything there is to know about polygraphy. I want to hear about people's experiences. What are the things that I need to be aware of? What kinds of information is out there, and where can I find it?
