So I was recently married and one of my wife's friends made a comment on the wedding day about her favourite memory of them was being naked in a hotel. I asked my wife later what she meant and she laughed it off saying they shared a room at a function and she got up through the night for the loo and was naked and her friend laughed at this. I'm not convinced. I know this was before we were met but I have the feeling she's lying to me about it. My last wife left me for another woman so I'm pretty nervous about this sort of thing. It may well be as innocent as she says but I really need clarity. Should I ask her and if so how do I approach it?
