I've seen links on here before to some excellent info in NPD - what it, how to recognise it, how it works, that sort of thing. Was in relation to spousal relationships IIRC but utterly relevant to her situation I feel. I told her about it and she asked me to look it up but I'm not having any luck finding what I'm after.
There was great stuff about co-dependancy too, can't find that either. Must be doing summut wrong 
Can anyone help?
