It’s the only way to know you’re really in love, when you ask the question would it be harder to watch him die, or to know he’ll watch me die? Is there more mercy in being the one who does the watching or in being the one who does the dying? It’s when you realize what mercy-killing actually means, it’s when you actually care to the point of tormenting worry. It’s not roses and white horses, it’s fucking brutal and it can send a person running for the hills. To love is brave.
