Just logged onto Facebook for the first time in ages. There is a message from my last ex but one. The immensely twatty one who alienated most of my friends and family, got prosecuted for fraud and in the middle of being prosecuted for fraud, announced he wanted an 'open relationship' (translation: to shag other women) even though I'd been worrying myself sick about him (I was very young and very stupid, which is my only excuse). I am also almost certain he cheated on me before that.
He even whined about being punished enough after his pathetically light sentence, at which point I lost all respect for him.
The message says hello, and that he didn't send a friend request because having been such an 'unmitigated sod' to me he didn't know how it would be received.
It was ten years ago but I doubt he's less of a twunt now. I am happy in my life and happy not having contact with him ever again.
