I have been told that having a polygraph done on my husband may be a good way to know if we are truly at ground zero and may help us to move forward. How accurate is a polygraph? Why would you advocate for or against a polygraph for an unfaithful spouse that has a history of lying, misrepresentation and trickling the truth? He assures me, again, that at this point, he has disclosed everything, but I have heard that so many times, I don't know how to move forward and believe that is true. Could a polygraph, and confirmation we are at ground zero, help us move forward in our healing?
