I think the same is true with a man politely trying to let the interested woman know that he’s not. And it’s not unique to women. It’s about taking a hint (or two). The only thing I might add from my perspective is that it’s easier for men with either a keen sense of rejection or a lack of confidence to take those hints easier. Men with greater self-confidence may try to pursue a bit harder. I’m not making any claims but just speculating. Thanks for the interesting article!
