Monday's question came from Jessica in Riverdale.
She wrote: "I've been in a relationship for 10 years and had three kids by a man whom I loved, but he cheated on me. I left him in 2012. He started a relationship with the girl he cheated on me with, but I still love him. He still flirts and we have sex sometimes. Should I say something to his girlfriend or leave it alone?"
Val, Ji, Ryan and sex-advice columnist and author Dan Savage weighed in.
