I do think there really is something in that whole 'feigned disinterest' thing: some men truly do think that women are playing hard to get (and of course, some may well be).
Is anyone else reminded of the whole Mr Collins proposal debacle in Pride and Prejudice?!
'...As I must therefore conclude that you are not serious in your rejection of me, I shall choose to attribute it to your wish of increasing my love by suspense, according to the usual practice of elegant females'
And Elizabeth's perfect response...
'I do assure you, Sir, that I have no pretension whatever to that kind of elegance which consists in tormenting a respectable man. I would rather be paid the compliment of being believed sincere. I thank you again and again for the honour you have done me in your proposals, but to accept them is absolutely impossible. My feelings in every respect forbid it. Can I speak plainer? Do not consider me now as an elegant female, intending to plague you, but as a rational creature, speaking the truth from her heart.'
These buffoons of men who persist and persist harm the situation for everyone. For the women they annoy, for the good men who have no idea that this sort of harassment goes on and so don't understand why women brush them off when they approach them, and for themselves ultimately, since again, most women's default mode, after so many repeated instances of low-, medium- and unfortunately high-level pestering is to turn away from them. Lose/Lose all round.
