Totalitarianism has won over humanity; Winston is one of the masses now, putting his real self aside for the Party, for Big Brother. Still, he has ambiguous feelings and is haunted by memories of a former time, but he has effectively convinced himself that these feelings and memories are false.
The meeting with Julia resolves some unanswered questions: She did indeed betray Winston, in the same way that he betrayed her. She is becoming like the other women in the novel, sexless and undesirable, just as a woman of the Inner Party should be. When Winston and Julia meet, they repeat each other’s phrases, just like Mr. Charrington did earlier in the story, a subtle device to show that they are truly indoctrinated. They are using the diction and the speech patterns of the Party.
Ultimately, Winston loves Big Brother, and will, presumably, spend the rest of his life loving him and waiting for the bullet in the back of his neck to set him free.
