I took this quiz and got:

Agnes Wickfield is the serene heroine of Dickens' David Copperfield. David thinks that Agnes is exemplary, but he doesn't realize that Agnes loves him. Throughout the novel Agnes tries to be selfless, even making friends with David's wife. She is very loyal to her family, too. She detests Uriah Heep's abuse of her father, and heartily refuses to marry him and compromise her beliefs. In the end, Agnes' patience wins through, and she is able to marry David, the man she has loved quietly for many years.

...which seems to pretty much sum me up, not counting the pining away for a married man thing ;)
