Hi Natalie, since you are walking on thin ice, and supposing the birthday you are talking about is a wedding anniversary, isn't showing up as Natalie on this event a bit on the insensitive side? Maybe your wife would like to have the man she married with her, in male attire, for such an occasion. Sorry, not meaning to be rude. But I don't think a wedding anniversary should be about Natalie, it should be about celebrating your couple. Was it your wife who brought up the possibility of having you as Natalie at the dinner? Or was it you? If it was you, do you think your wife is 100% onboard with it? Or have you been pushing the thing until she accepted to consider it?
I sense a lot of pink fog in your latest posts and am worried. Many CDs tend to get very oblivious of their wives' feelings when it happens.
