“You are part of my existence, part of myself”. This is part of Pips last speech to Estella and Mrs. Havisham to which he opens up and displays his true feelings infront of both of them. From the first time that Pip saw Estella to the day of the speech Pip always had Estellas shadow following him for which he judged his decisions around. With Pip finally opening up he breaks the facade and shows his feelings in full effect.

The way Pip uses “part of” in repetition allows him the emphasise Estella becoming part of him and his existence. While Pip doesn’t literally have Estella part of him he means it figuratively with living up to Estellas expectations his primary goal, affecting all those around him.
