Shortly after the narrator relates Anne's and Captain Wentworth's history, we learn that Anne (unsurprisingly) regretted breaking off their engagement and would never advise anyone to do the same, right? Yet when she and Captain Wentworth finally get the chance to discuss it, she never apologizes for (what we were earlier told she herself saw as) her mistake (like, for example, Elizabeth Bennett did to Mr. Darcy) but defends her decision. Huh?
