She had something good going for her then PL. My ex sounds a bit like yours - when I found out, I started screwing her best friend which resulted in the pair of them fighting in the middle of the high street, complete with ripped clothes and trying to scratch each others eyes out. Didn't exactly help either relationship but it was good for my ego to have them fighting over me, and certainly helped me move on.

I've always thought that life is too short to worry about failed relationships, but I have fond memories of that afternoon.
