He’s very cold and distant, almost like he’s dissociating all the time. He only acts like that because he doesn’t want to get too close to anymore because every he got close with ended up dead. He would rather have the whole world be completely wiped out and it be only you two left than lose you forever. You’re the only person capable of making him even a little happy. He barely sleeps, so he sometimes just watches you sleep. He’s completely in love with you.
