Willoughby had a correspondence with Marianne, which by then was only for aknowledged engagements; and brought her in his carriage to make her visit his aunt's house.
Nothing such from Mr Bingley!
There was a visible preference, but not to the point of any breach of admitted intercourse between people who were not engaged.
Above all, he was led to believe that she did not return his regard.
Captain Wentworth himself, whom I have found somehow exceedingly scrupulous, was expecting to know Louisa's own expectations, and to propose her if she had; which Mr Bingley certainly would have done, had he had the least suspicion of Miss Bennet's wishes! The only thing wrong was not to enquire further, and to admit Mr Darcy's assertion, maybe less qualified in matters of love than in others. But can anyone tell me how, by which mean(s), he could have enquired to know Jane's wishes?
