I think you wife shoudl take the lead here too. It sounds as if your time being Nancy is being is reduced because she is staying with you and your wife wants you to be happy. I would think that this would be something she wouldn't want to deal with right now. I can't see what purpose it would serve to tell her now. But I would explore it more with your wife. I would want to know why she thinks it's a good idea now at this point to tell her?
