“I know. I have no hope that I shall ever call you mine, Estella. I am ignorant what may become of me very soon, how poor I may be, or where I may go. Still, I love you. I have loved you ever since I first saw you in this house.”

– Charles Dickens

Great Expectations, Chapter 44. Even though Pip knows he will never win her, he declares his love for Estella. Oh the agony of unattainable unrequited love! In Pip’s case it is more an obsession.
