Dear ________________,
I can't believe you haven't caught on. Actually, you probably have, you just don't want to confront the situation. I don't blame you, really. In your place I'd play dumb as well. But please PLEASE please, for the sake of my sanity, stop dancing around it.
I don't know what I expect of it. Really, I don't think that there's any way it could go well in the long run, but I do know that it needs to be spoken of before I lose my mind. We'll just talk about it and then leave it at that. We can forget the conversation ever happened, I'm fine with that. Well, I won't be fine with that, but I'll get over it. I promise. I really do bounce back quickly.
We really should just have the conversation and then drop it. I don't want it to complicate our lives any. I want to still have a relationship of sorts with you, just please understand that my sanity depends on this conversation happening. Please. Please.
I know you know that I know that you know. Just say something!
Let's just meet somewhere and talk. I won't even crack jokes about your silly hat. We don't even have to look at eachother during the conversation. That actually might be better. Let's talk while we go for a walk and both just keep our faces forward. That'd be fine.
I'm rambling, I know, but you're used to it.
I have to go to bed.
Call me. Text me. Message me. Write me a letter. Show up at my house. Show up at my school. Do something.
Let's get this talk out of the way now so we won't have to deal with it later.

Love always,
Me
