“That’s not an apology, simply an acknowledgement that I was right.”
This chapter is the one that contains Darcy’s letter to Elizabeth. After he explains his part in Bingley and Jane’s break-up, he says, “On this subject, I have nothing more to say, no other apology to offer.”
Explaning his actions was an admission of guilt, not an apology.
Did he ever say he was sorry for meddling?
Oh, wait! I get it. In this case, Darcy’s using the other definition of apology: “a formal jusitification or defense.” Ahhh, so that’s what he was doing.
Now that sounds more Darcy-esque to me.
