I think you vastly over-estimate the ability of most people to pretend

evolution has equipped us with biased beliefs about such things is that

Your girlfriend will not be satisfied with your being polite and never
bringing up the subject of what you think of her. She will ask you, if
need be. And she will look closely to see if you believe what you say.
