I would sit down by myself and think about it for a long, long, time. Unfortunately it sounds a lot like you are about to play that game called Russian roulette. My advise is not to say a thing until you are absolutely without a shred of doubt certain that she is going to be delighted to learn that you dress. Ask youself some questions, such as, "will this end my marriage?" "Will she get the house?" "Where will I live after this?" "Can I afford to pay for keeping two homes?" "Should I risk everthing?"
