"Because you didn’t love me anymore!" Sirius bursts, and the sentence is so absurd that Remus has no retort, and Sirius can finally speak a full sentence. "Or maybe... maybe you never loved me." Sirius wipes his eyes aggressively. "But I... I loved you, and I wanted you, and for a while, when we started, I thought you loved and wanted me too. I thought, I thought we could be happy together, like James and Lily. I thought we were  perfect for each other. I’d wanted you for so long. But... but you started pulling away, and giving me less affection, and you’d fuck me but not cuddle after, and you wouldn’t talk to me about your missions and were missing moons, and it felt like we weren’t even friends anymore. It was like, the more I gave to you, the more you pulled away."
