It's always interesting to me how differently people can interpret novels. To me, a significant part of "Pride and Prejudice" is that Darcy tries very hard to conceal his regard for Elizabeth and as a result sends very mixed messages. When he feels he has paid her too much attention at Netherfield, he pulls back and shuts down (the last day especially). At Rosings he sends more mixed messages, staying away from the parsonage for the first few days when the colonel comes to visit. The 50 miles of good road conversation seems to illustrate his state of mind very well. When he thinks he has gone too far with personal conversation, he immediately moves back physically, picks up a newspaper to use as a barrier, and changes the subject and his tone of voice. It's almost as if an alarm bell went off in his head and he started doing damage control.
And another significant part of the story (to me, anyway) is that Elizabeth is not like her mother and Lydia. The book shows several times (even before Dacy's letter) that Elizabeth is willing to change her mind. And I'm not sure what you mean about expressing her opionions loudly. She does give her opinions freely at Netherfield. She is extremely frank with Jane, and to a lesser extent with Charlotte and her aunt. And I know some readers believe that she denounces Darcy roundly to half the county, but I don't think that is what the book shows.
