Henry developing romantic feelings for Fanny is an example of situational irony because he was the one who set out to make her fall in love with him. Henry—and readers by extension—did not expect to genuinely want to make Fanny his wife. His sister Mary’s response to his declaration of love for Fanny captures readers' surprise as well:
The surprize was now complete; for in spite of whatever his consciousness might suggest, a suspicion of his having any such views had never entered his sister’s imagination; and she looked so truly the astonishment she felt, that he was obliged to repeat what he had said, and more fully and more solemnly.
The situational irony at the heart of Mansfield Park is that, while most of the characters talk about the importance of marrying for love, marriage in practice is much more about strategy and socioeconomic advancement. This tension is particularly apparent in how the Bertrams respond to Henry asking for Fanny’s hand in marriage. In Chapter 36, Edmund centers the importance of romantic love in his reaction to the proposal by trying to convince Fanny that she will come to love Henry one day if she gives him a chance:
Unlock with LitCharts A+Edmund now believed himself perfectly acquainted with all that Fanny could tell, or could leave to be conjectured of her sentiments, and he was satisfied […] She must be used to the consideration of his being in love with her, and then a return of affection might not be very distant.
After ten years of neglecting and looking down on Fanny, Lady Bertram suddenly sees her as beautiful and approves of her as a family member, simply because a wealthy and desirable man (Henry) has proposed to her—an example of situational irony. Here the narrator captures Lady Bertram’s ironic internal thoughts on the matter:
Unlock with LitCharts A+Lady Bertram took it differently. She had been a beauty, and a prosperous beauty, all her life; and beauty and wealth were all that excited her respect. To know Fanny to be sought in marriage by a man of fortune, raised her, therefore, very much in her opinion. By convincing her that Fanny was very pretty, which she had been doubting about before, and that she would be advantageously married, it made her feel a sort of credit in calling her niece.

Henry and Maria having an affair near the end of the novel is an example of situational irony because readers are, by that point, convinced that he has given up his flirtatious, fickle ways in order to be faithful to Fanny. Fanny’s confused reaction to reading the newspaper clipping that revealed the affair captures the irony of this moment:
Unlock with LitCharts A+“It is a mistake, Sir,” said Fanny instantly; “it must be a mistake—it cannot be true—it must mean some other people.” She spoke from the instinctive wish of delaying shame, she spoke with a resolution which sprung from despair, for she spoke what she did not, could not believe herself.
