Dear Steve and Shirley, I am a 30 year old happily married female with a beautiful family. I need our advice on how to handle a little situation with my ex and my sister. Ten years ago, I had sex with a guy and it was like a “friends with benefits” situation because we both were young. He and I have sort of kept in touch over social media, but have not seen each other in years, until recently, when I ran into him at the mall and he told me that he met my younger sister and had been hanging out with her...........
