What should I do about this?
A little background before I start. I am a divorced woman and was on a site called Adult friend finder. AS I was there I discovered someone who I know who is married who is pretending to be single. He showed me his picture and its him .When he signed up he was married it shows sign up date 2009 and we are in 2017 and he is still on there he also told me he had a one night stand at a conference. MY question I know someone who knows him should I tell the person. I feel so guility and don't sleep well because of this secret, I feel if that was me I would want to know . What should I do thanks
