What do Julia and Winston say when they meet again? Book III Chapters 1-6

They saw each other once after being released, purely by chance. He followed her on her walk, always a few feet behind. Eventually she stopped and he put his arm around her waist, but felt revulsion at the thought of making love to her. She did not respond; her body felt rigid and lifeless. They sat down on a bench with some distance between them. After some time, she told him, "I betrayed you." He told her the same. They agreed, through a distant conversation, that there are some things they can do to you that make you think and care only about yourself. After that, it is impossible to ever feel the same way towards one who you loved. She made an excuse to leave, and they both feebly suggested they should meet again, knowing they never would.
