How do I tell him? He has accused me of having an affair, which I haven't. He said he knows about affairs and how they work - I asked him how he was such an expert and he confessed because he had one 20 years ago with s married woman who is now a close friend of his. She has always been weird with me and now I know why. She has always asked to see H on his own for dinner and theatre. I have always been flexible and agreed to it. Who is the mug here - him or me? (Bit of an aibu as well)
