The letter which she wrote on this occasion to her sister will prove what she felt.
"My dearest Lizzy will, I am sure, be incapable of triumphing in her better judgement, at my expense, when I confess myself to have been entirely deceived in Miss Bingley's regard for me.

But, my dear sister, though the event has proved you right, do not think me obstinate if I still assert that, considering what her behaviour was, my confidence was as natural as your suspicion.

I do not at all comprehend her reason for wishing to be intimate with me; but if the same circumstances were to happen again, I am sure I should be deceived again.

Caroline did not return my visit till yesterday; and not a note, not a line, did I receive in the meantime.

When she did come, it was very evident that she had no pleasure in it; she made a slight, formal apology, for not calling before, said not a word of wishing to see me again, and was in every respect so altered a creature, that when she went away I was perfectly resolved to continue the acquaintance no longer.
