'Your continuous reaching out is a painful reminder of how cruel you really were then and now, 'Let me make this VERY clear. (If I haven't already) You are not my family.

'You are not my friend. So I'm writing to tell you one last time to stop exploiting our tragedy in order to restore your "nice girl" persona.'
