We have had ongoing issues with infidelity and pornography throughout our 20+yrs of marriage. Right now we are in EMSO and my husband is very engaged. However I have been down this path where we go through counseling and he seems committed then he goes back to his old patterns. I think we are at ground zero but he has gotten so good at hiding his indiscretions that I don't know what to trust. Would it be appropriate for me to request that he take a polygraph? Also is it appropriate to ask him to give me his cell phone and social media passwords?
