This is something that I read once, geared towards people who have been abused, but it occurs to me that anyone could use it, and I find that it can be very cathartic. I know that with kinky relationships there's a sort of propriety, maybe even after the relationship's over, that you don't talk to some people a certain way, and it might be helpful to get past that for some people, even though the target will never see.
So here's what you do: Comment anonymously and write a letter to an ex, something that you've wanted to say, or would say if you could. It can be serious, sad, angry, petty, trivial. It can also be happy, positive, nostalgic. Just something you couldn't say to their face. Put it down here and let it go.
