To whom it may concern:

- how do you break up with a friend anyway?
and
- why is it so hard to break up with someone who hasn't treated you well?
and
- how is it possible to feel relieved and sad and slightly desperate and optimistic and aggrieved all at the same time?

and to the person in question:
- please have the decency to respond well to my letter, phrased as positively and maturely as I could. I can't stand any more recriminations now, and I do honestly wish you well, whether you believe it or not.
