Read it through once

“You, who so well know my feelings towards Mr. Darcy, will readily comprehend how sincerely I must rejoice that he is wise enough to assume even the _appearance_ of what is right. His pride, in that direction, may be of service, if not to himself, to many others, for it must deter him from such foul misconduct as I have suffered by. I only fear that the sort of cautiousness to which you, I imagine, have been alluding, is merely adopted on his visits to his aunt, of whose good opinion and judgment he stands much in awe. His fear of her has always operated, I know, when they were together; and a good deal is to be imputed to his wish of forwarding the match with Miss de Bourgh, which I am certain he has very much at heart.”
