What does the speaker mean by saying "I didn't think so"? Hi guys, This is an exchange from a novel. Could you please help me understand 'I didn't think so' said at the end? "No, she did not send me here. I sent myself." "I don't understand." "She stayed with me at first, but she missed him. It made her unhappy... so I decided it was time to spend some quality time with Charlie." "But now you're unhappy." "And?" "That doesn't seem fair." "Hasn't anyone ever told you? Life isn't fair." "I believe I have heard that somewhere before." "So that's all." "You put on a good show. But I'd be willing to bet that you're suffering more than you let anyone see. Am I wrong? I didn't think so."
