Like Amelia in Lovers' Vows, Fanny is unmoved by the temptations of wealth, status and sexual conquest. When she is given the rare opportunity to express her feelings, she does not hold back, as is shown in her gentle, but spirited, defence of her right to her 'negative’:
I should have thought …. that every woman must have felt the possibility of a man's not being approved, not being loved by some one of her sex, at least, let him be ever so generally agreeable. Let him have all the perfections in the world, I think it ought not to be set down as certain, that a man must be acceptable to every woman he may happen to like himself…. In my situation, it would have been the extreme of vanity to be forming expectation on Mr Crawford… How then was I to be - to be in love with him the moment he said he was with me? How was I to have an attachment at his service, as soon as it was asked for?"' (MP, p. 353)
This speech is remarkable for its encapsulation of the paradoxes of courship conduct for women, particularly those of a low status. Fanny's ‘settled dislike' of Crawford is not enough for Sir Thomas, or indeed Edmund, because Crawford is perceived as a socially acceptable ‘catch'; yet, paradoxically, it is precisely Fanny's lowly social status which precludes her from forming any expectations of Henry in the first place. Furthermore, when she is condescended to be noticed by a man of means, a man whom she has no right to consider in the first place, she is immediately expected to switch on her feelings, 'as soon as it was asked for’. […] Fanny, of course, is not in Amelia’s position of choosing her own husband, but she nevertheless exercises her right to refusal, as do most of Jane Austen's heroines. […] Austen has Henry Tilney advocating ‘women's power of refusal' in Northanger Abbey, but in Pride and Prejudice she conveys the limitations of a woman's 'no' in Mr Collins's and Darcy's refusal to accept Elizabeth's refusal. […] In Mansfield Park, Henry's reluctance to accept Fanny's refusal is proof of his gross selfishness. Even when she is softened by his conduct at Portsmouth, she still hopes to be released from his attentions: 'might not it be fairly supposed, that he would not much longer persevere in a suit so distressing to her?' (MP, p. 414).
