Jane Austen said this quote

“ She certainly did not hate him. No; hatred had vanished long ago, and she had almost as long been ashamed of ever feeling a dislike against him, that could be so called. The respect created by the conviction of his valuable qualities, though at first unwillingly admitted, had for some time ceased to be repugnant to her feelings; and it was now heightened into somewhat of a friendlier nature, by the testimony so highly in his favour, and bringing forward his disposition in so amiable a light, which yesterday had produced. But above all, above respect and esteem, there was a motive within her of good will which could not be overlooked. It was gratitude.--Gratitude not merely for having once loved her, but for loving her still well enough, to forgive all the petulance and acrimony of her manner in rejecting him, and all the unjust accusations accompanying her rejection. He who, she had been persuaded, would avoid her as his greatest enemy, seemed, on this accidental meeting, most eager to preserve the acquaintance, and without any indelicate display of regard, or any peculiarity of manner, where their two selves only were concerned, was soliciting the good opinion of her friends, and bent on making her known to his sister. Such a change in a man of so much pride, excited not only astonishment but gratitude--for to love, ardent love, it must be attributed; and as such its impression on her was of a sort to be encouraged, as by no means unpleasing, though it could not exactly be defined. ”
