I want you to know that I love you, and that I won't stop, not as long as you're walking around and loving me back. You're such a wonderful guy, always kind, always willing to make things work and I don't deserve you. I've slept around... a lot. It was before I found you again but it still feels so wrong.
I was hurting and I felt so alone, so I drank. I won't blame sluttiness on drinking, but it sure didn't hurt. If I was normal I'd be filled with disease right now but I'm not, so you'd never know. That enough should be worth leaving me for, but there's something else.
My heart belongs to someone else. Not that part of it isn't yours, which it always will be, because I do love you. But this other person, he's, it's so hard to explain. He's my family, my best friend, my other half. He's been that for centuries and will be long after you're gone, honestly, he's been that for most of my life.
I think you suspect some of this already. You know how close we are, and you- there's a bond that you can't break, no matter how much I hate him, or how mad you are about something he's said to me. I think you know about Lynn too, because the math just doesn't add up with her. I'm pretty sure Frankie will be yours, though, and you will be there for Lynn as she grows.
You are the best thing to happen to me, and I'm so sorry about everything. You deserve better, and I deserve to be alone.
