Betrayal or not betrayal: that is the question

'It is my brother's attentions to Miss Thorpe, or Miss Thorpe's admission of then, that gives the pain?'

'Is not it the same thing?'

'I think Mr. Morland would acknowledge a difference. No man is offended by another man's admiration of the woman he loves; it is the woman only who can make it a torment.'

(Excerto do livro Northanger Abbey de Jane Austen)
