Perhaps this is not what you intend, but you seem to be suggesting Lizzy would accept a man for who she has no esteem if she respected him. While I agree Lizzy’s idea is less than only the deepest love will tempt her into marriage (P&P2) I don’t see any evidence she believes it appropriate to accept a man with only the possibility she can learn affection for him at some point in the future. I think Lizzy agrees with Jane that a woman ought to feel something in the nature of regard and esteem before accepting a man:

"Remember that she is one of a large family; that as to fortune it is a most eligible match; and be ready to believe, for everybody's sake, that she may feel something like regard and esteem for our cousin."

"To oblige you, I would try to believe almost anything, but no one else could be benefited by such a belief as this; for were I persuaded that Charlotte had any regard for him, I should only think worse of her understanding than I now do of her heart." (24)
