I never tell women how much I make I remember I did once.

It is none of her business how much you make. Women ask you what is your occupation to get an idea of how much you make. Telling her what your occupation is the most you should tell her in regards to your finances.
Y'all overlooking the part where he said fiance? I'd assume if a chick is about to marry you, then she goin know how much you make. Even if for some unimaginable she will figure out just based on how you living (what car you drive, restaurants you goto, what/how you spend your money)
