The classic gender stereotypical joke is that women are selfish, so she doesn't "see" him (as a viable partner) bc while he's there, he's not "one of the good ones". Then, regardless of whether he is and she simply does not see it, or perhaps he is legit not, either way he's upset at her brazenness - like even if it were true, why rub it in his face like that? Just keep those kinds of thoughts to herself!
