"The unqualified truth is, that when I loved Estella with the love of a man, I loved her simply because I found her irresistible. Once for all; I knew to my sorrow, often and often, if not always, that I loved her against reason, against promise, against peace, against hope, against happiness, against all discouragement that could be. Once for all; I loved her nonetheless because I knew it, and it had no more influence in restraining me, than if I had devoutly believed her to be human perfection." (181)
Pip realizes he isn't in love with Estella the person, and that maybe the love isn't good for him self. But still, he loves her.
Dreams, Hopes, plans
"She had adopted Estella, she had as good as adopted me, and it could not fail to be her intention to bring us together. She reserved it for me to restore the desolate house, admit the sunshine into the dark rooms, set the clocks a going and the cold hearths a blazing, tear down the cobwebs, destroy the vermin—in short, do all the shining deeds of the young Knight of romance, and marry the Princess." (181)
Pip thoroughly believes that his benefactor is Miss Havisham, and that she is helping him so that he can marry Estella. However, this is probably a subject of Pip's unhealthy obsession with Estella.
"I would not have gone back to Joe now, I would not have gone back to Biddy now, for any consideration: simply, I suppose, because my sense of my own worthless conduct to them was greater than every consideration. No wisdom on earth could have given me the comfort that I should have derived from their simplicity and fidelity; but I could never, never, never undo what I had done." (254)
Pip's world is crashing in around him, as he realizes it's not Miss Havisham's elicit plan to have Pip marry Estella. This leads him to begin to regret the bridges he burned cutting off his friends and family from his new life.
"Look'ee here, Pip. I'm your second father. You're my son—more to me nor any son. I've put away money, only for you to spend." (251)
The Convict seems to be the only generous person in the story, and he tries to start off on a good foot with Pip; he tries to treat Pip like a lost son/friend. Pip, however, doesn't return the sentiment, as he doesn't value anyone who doesn't fit into his version of his future.
Love is a risky business; it can make you burn bridges and change yourself; it can be the best experience of your life, but in the end you may end up hating it.
At the end of the section, Pip meets his long-time benefactor, the Convict. Up until this point, Pip has had a vision in his mind of Miss Havisham having him and Estella married. This discovery brings that world crashing down around him, which makes him reject the Convict and regret all the bridges he burned with Joe and Biddy.
