I've decided it's better by letter.
I can't do this face to face. You argue and outlogic me, or cry or shout. Whatever, I end up feeling guilty and more angry at you. So yes, letter is best.
There's no easy way to say this. I don't want to hurt you. but I will, telling you this. I want you to leave. I want you out of my life. Completely.
There, I said it!
They say writing things down gets rid of those demons living inside your head.
But I haven't written it down yet. Please, may I borrow paper?
