"I don't care that you said it," Sirius said truthfully. It had only really hurt when Remus repeated it, then tried to pass it off as something he'd thought of himself instead.
Peter really did think he had Sirius all figured out, didn't he. That Sirius hadn't had dreams about both of them before he'd even known being with boys was an option. That friendship couldn't lead to deeper feelings, and that loving more than one person meant those feelings weren't valid. Why was everyone so sure that their idea of what love was or meant was the only correct option?
"You know what Peter? I'm getting really sick of people deciding they know me better than I know myself. I don't think it's such a crazy stretch to believe that years of emotional and physical intimacy with people could lead to deeper feelings, and I don't think that having them for more than one person means they're not real! I've accepted that neither of them feel the same way, but I'm done with people telling me I don't know my own heart. Okay? So think whatever you want, but you don't know what I feel. And you don't get to decide for me what is and isn't valid."
He stuck his hands in his pockets and leaned against the wall.
"You're not fucking evil Peter. You've already met someone who likes you, and I'm really sorry you lost her, but that just proves that you can do it, and you could do it again. And it matters because, surprisingly, it's actually really hard to stay friends when you don't ever see someone. If Remus has to choose between me and James and Regulus who do you think he's going to pick? I've accepted that I can't be with him but that doesn't mean I don't want to see him outside of full moons! But that's something for the future and not something I have any control over so what's the fucking point of dwelling on it?"
He pushed off the wall and started walking again.
"You can come if you want but I'm done talking about this. Think whatever you like about me, I don't give a shit."
