Just so we are clear husband, you and I agree. Its harder to be the betrayed husband than it is to be a betrayed wife. Some might disagree. I know that OW's H agrees, and most men that I have asked.
I see what you mean about being mysterious. Your Vegas trip? Mysterious. You ignoring that W might want coffee too? Borderline insensitive. You need to show that your life WILL go on without W, you don't need to show that you hate W.
