She is not your friend. She is someone who probably enjoys controlling you and making you feel less worthy than her. She obviously thinks you need her more than she needs you. Prove her wrong. I would not let it fizzle though, I would tell her you are moving on and are no longer prepared to put up with her behaviour. If you can't face her personally then email or write to her, put yourself in control and ask her not to get in touch with you again. What she says about you to other people, you have no control over/ Personally, I would not want 'friends' who believe things about me or my family said by someone who is malicious. They are not friends either.
