It's so sad just how self centred and hurtful they can be. In order to deal with his guilt he's going to shove OW into the faces of his family and you. In some bizarre way he thinks this makes what he has done legitimate. I guess he fakes it until he makes it! So he just carries on as though he's done nothing wrong. He pretends while hurting everyone else around him at a time of great grief for all involved. It's the same old same old...it's all about them, baby. You do what you feel best doing Livin4ME, nothing you do aside from making a horrible scene (which you won't do) would be inappropriate. You are courageous and loving just to go, be proud of that fact. You are way ahead of him!
