maybe I should keep quiet-but from what you've said, I think you will find it hard to get rid of her -was in similar position once-she's not a friend, but likes the idea you 'need' her, if you back off she'll be glued to you for few days when she realises, but then nasty again.Block her on fb-then she'll know-WHEN she turns nasty (and she will) haven't you got one other friend/family that you can rant at on the phone? it will do you good
