You, him and your expectations.
Most of us construct our prototype of the perfect partner from a novel, a movie or even a mysterious passing stranger. Then we let our imagination run wild and we ascribe all sorts of wonderful qualities and abilities to our dream partner. They are kind, considerate, loving, strong, sexy, mysterious, powerful, rich etc etc
