She was now struck with the impropriety of such communications to a stranger, and wondered it had escaped her before. She saw the indelicacy of putting himself forward as he had done, and the inconsistency of his professions with his conduct.

– Jane Austen

Pride and Prejudice, Chapter 36. Elizabeth looks back with hindsight on her meetings and conversations with George Wickham. She starts to see those conversations in a different light, realizing now their "impropriety" and "indelicacy" and the "inconsistency" of what he was saying with his conduct. She is shocked at how blind she was.
