Guess whose the benefactor! Not Havisham that's who!

The entire reason that Pip wished to be a gentleman laid in the fact that he believed it was all part of his training so that he might be betrothed to Estella. Through this line of reasoning he believed that it was Miss Havisham who sponsored him to come to London and learn the necessary skills to be a gentleman. All of this is thrown to the wind when Pip discovers his real sponsor to be none other than the convict whom he had helped in the marshes. Since it was not Miss Havisham providing the money, Pip realizes that he was never meant for Estella, and that Ms. Havisham merely used his confusion on the identity of his sponsor to further entangle his heart. With no chance of gaining Estella, Pip realizes that he has no reason to become a gentleman anymore, and that he has wasted his life in pursuit of something he can never have. At this point most would give up, but Pip is too attached to Estella and will never be able to let her go. And so Miss Havisham succeeds in not only breaking, but ripping apart his heart.
