"But his pride, his abominable pride - his shameless avowal of what he had done with respect to Jane - his unpardonable assurance in acknowledging, though he could not justify it, and the unfeeling manner in wich he had mentioned Mr Wickham, his cruelty towards hwom he ahd not attempted to deny, soon overcame the pity which the consideration of his attachment had for a moment excited. She continued in very agitating reflections till the sound of Lady Catherine's carriage made her feel how unequal she was to encounter Charlotte's observation, and hurried her away to her room." (end of chapter 34)

Nothing there of looking hard at herself. She is sorry for Darcy for a moment or so, until she recollects all the things he has said to reinforce her ill opinion of him.
I'm sorry if I accidentally scooped you into the unconscious attraction basket, Adrian.:-) But I do still disagree with the assertion that she didn't quite know what her feelings were towards Darcy. I think she knew exactly what she meant when she told him that she would not have accepted him even if he had 'behaved in a more gentlemanlike manner' - in other words, made his proposal less arrogantly, without denigrating her family.
