Following is the context of the quotation from the last chapter of Austen's last completed novel, released posthumously:

Persuasion by Jane Austen
Chapter XXIV

Who can be in doubt of what followed? When any two young people take it into their heads to marry, they are pretty sure by perseverance to carry their point, be they ever so poor, or ever so imprudent, or ever so little likely to be necessary to each other's ultimate comfort. This may be bad morality to conclude with, but I believe it to be truth; and if such parties succeed, how should a Captain Wentworth and an Anne Elliot, with the advantage of maturity of mind, consciousness of right, and one independent fortune between them, fail of bearing down every opposition? They might in fact, have borne down a great deal more than they met with, for there was little to distress them beyond the want of graciousness and warmth. Sir Walter made no objection, and Elizabeth did nothing worse than look cold and unconcerned. Captain Wentworth, with five-and-twenty thousand pounds, and as high in his profession as merit and activity could place him, was no longer nobody. He was now esteemed quite worthy to address the daughter of a foolish, spendthrift baronet, who had not had principle or sense enough to maintain himself in the situation in which Providence had placed him, and who could give his daughter at present but a small part of the share of ten thousand pounds which must be hers hereafter.

Sir Walter, indeed, though he had no affection for Anne, and no vanity flattered, to make him really happy on the occasion, was very far from thinking it a bad match for her. On the contrary, when he saw more of Captain Wentworth, saw him repeatedly by daylight, and eyed him well, he was very much struck by his personal claims, and felt that his superiority of appearance might be not unfairly balanced against her superiority of rank; and all this, assisted by his well-sounding name, enabled Sir Walter at last to prepare his pen, with a very good grace, for the insertion of the marriage in the volume of honour.

.......................

It cannot be doubted that Sir Walter and Elizabeth were shocked and mortified by the loss of their companion, and the discovery of their deception in her. They had their great cousins, to be sure, to resort to for comfort; but they must long feel that to flatter and follow others, without being flattered and followed in turn, is but a state of half enjoyment."
