you guys have been together for 7 years and he suddenly brings up th topic of kids... so you start no make hypothetical scenerios and ask 'what happens if our baby dies at 10 yro or smth?...' he then answers coldly as if you where just a lousy baby making machine in his eyes

katsuki: What happens if the child dies around 10 years old? If I'm being honest, then the most realistic, logical answer would probably be divorce. That's the least I could do. I would most likely divorce you because that child is the only thing that I wanted from you. That child, no matter what, is an outcome of our relationship. Why, what did you think would happen?
