She did hit me with this: The motion picture the OM is making is going to star a famous heavy metal singer. The singer's band has asked OM to shoot their videos. He already has done one, now they are going to do another one. W is going to go to the shoot, but it involves an overnight. Obviously I am not happy about this. Given my circumstances, how should I approach this? I want to tell her I don't like it. Of course, in her mind it doesn't matter
I think you just tell her "Thank you for letting me know," and that's it. If she tries to go further and say anything about "nothing's going on," etc., then stop her and say "Look, I can't control what you do -- you're an adult -- but I'm not stupid, and we both know you're lying to me, so please just stop it," -- and walk away.
