re: How do you get over being hurt and betrayed?

Write a stinging, lashing letter telling the other person how glad you are they finally showed their true colors, because you wouldn't care to waste another minute with garbage like him/her.

I've actually written such a letter for a few of my friends--cruel, nasty, wounding, but enormously good fun to read--and never threatening or violent. I'll be glad to write one for you: my fee is $250 with one revision. Money well spent I assure you.
