Cassandra Clare said this quote

“ Your place is with me,” Jem said. “It always will be.”“What do you mean?”He flushed, the color dark against his pale skin. “I mean,” he said, “Tessa Gray, will you do me the honor of becoming my wife?”Tessa sat bolt upright. “Jem!”They stared at each other for a moment. At last he said, trying for lightness, though his voice cracked, “That was not a no, I suppose, thoughneither was it a yes.”“You can’t mean it.”“I do mean it.”“You can’t—I’m not a Shadowhunter. They’ll expel you from the Clave—”He took a step closer to her, his eyes eager. “You may not be precisely a Shadowhunter. But you are not a mundane either, nor provably aDownworlder. Your situation is unique, so I do not know what the Clave will do. But they cannot forbid something that is not forbidden by the Law.They will have to take your—our—individual case into consideration, and that could take months. In the meantime they cannot prevent ourengagement.”“You are serious.” Her mouth was dry. “Jem, such a kindness on your part is indeed incredible. It does you credit. But I cannot let you sacrificeyourself in that way for me.”“Sacrifice? Tessa, I love you. I want to marry you. ”
