“I can offer you my life, but it is a short life; I can offer you my heart, though I have no idea how many more beats it shall sustain”

“I can offer you my life, though it is a short life. I can offer you my heart, though I have no idea how many beats it shall sustain. But I love you enough to hope the rest of my life-whatever its length-happy, by spending it with you.-Jem.”

“You speak of sacrifice, but it is not my sacrifice I offer. It is yours I ask of you," he went on. "I can offer you my life, but it is a short life; I can offer you my heart, though I have no idea how many more beats it shall sustain. But I love you enough to hope that you wil not care that I am being selfish in trying to make the rest of my life - whatever length - happy, by spending it with you. I want to be married to you, Tessa. I want it more than I have ever wanted anything else in my life." He looked up at her through the veil of silvery hair that fell over his eyes. "That is," he said shyly, "if you love me, too.”

“You remember what else I said to you that day in the drawing room,” he said. “I want you to be happy, and him to be happy. And yet when you walk that aisle to meet him and join yourselves forever you will walk an invisible path of the shards of my heart, Tessa. I would give over my own life for either of yours. I would give over my own life for your happiness. I thought perhaps that when you told me you did not love me that my own feelings would fall away and atrophy, but they have not. They have grown every day. I love you now more desperately, this moment, than I have ever loved you before, and in an hour I will love you more than that. It is unfair to tell you this, I know, when you can do nothing about it.” He took a shuddering breath. “How you must despise me.”

“And now I need you to do for me what I cannot do for myself. For you to be my eyes when I do not have them. For you to be my hands when I cannot use my own. For you to be my heart when mine is done beating.”

“But just promise me something, okay? I know how girls get. I know how they hate their boyfriends having a best friend who’s a girl. Just promise me you won’t cut me out of your life totally. That we can still hang out sometimes.''Sometimes?' Simon shook his head. 'Clary, you’re crazy.'Her heart sank. 'You mean...''I mean that I would never date a girl who insisted that I cut you out of my life. It’s non-negotiable. You want a piece of all this fabulousness?' He gestured at himself. 'Well, my best friend comes along with it. I wouldn’t cut you out of my life, Clary, any more than I would cut off my right hand and give it to someone as a Valentine’s Day gift.''Gross,' said Clary. 'Must you?'He grinned. 'I must.”

“But that's what you're doing, isn't it? You're part of the fight just as much as the Shadowhunters on the ship—and I know you can take some of my strength, I've heard of warlocks doing that—so I'm offering. Take it. It's yours.”
