Dear Sirius,
Hi, hello. So, I wish I could do this in person, but as I've decided to stay out of everyone's lives, that's not really an option. So... here goes nothing.
I've been thinking about everything you said earlier, and everything Bellatrix said... and you're both right. What I did to you and James... I'm surprised you both still care about me, much less do everything you do for me. I never intended to do what I did. I love you both so much and I never wanted to hurt either of you.
Sirius, I... I am truly sorry for what I've done. I've treated you like shit, even without meaning to. I don't deserve your friendship, and all, and I am truly thankful for everything you've done for me. And I hope that, one day, I'll find a way to repay you. But for right now, it's probably best if I just... disappear. Because Bellatrix was right: I've tried so hard not to be like them that I've turned out worse than they could ever be. I hurt the people I love most without even trying.
Whoever your mystery woman is, she's lucky. I hope you two make it, because I can tell by the look in your eyes that you love her. By the way, I smelled a hint of a love potion in the flask. I hope it helps.
So good luck. And thanks for everything, truly.
Love, Marlene
