How does 1984 end?

Months after being arrested, poor Winston Smith is sent to Room 101, where every person who enters is faced with their greatest fear. For Winston, it’s rats. Musing on the impending rats-chewing-on-his-face scenario, Winston calls out, "Do it to Julia!" That's pretty much what O'Brien was looking for, so Winston gets to go back to being a happy member of the rat race. Released, Winston's heart is filled with love for the Party. Even when he and Julia meet again by chance at the Chestnut Tree Café, they feel apathetic towards each other. He has been successfully converted and destroyed.
