Also...people who use manipulation to control others do it for the boost to their self-esteem, the whole "I can make people do things..." She wants to keep you as a friend so she can continue to do this. If you aren't in her life, she loses the ability to control you...which is a blow to her self-esteem. It's not your job to build her self-esteem by being there for her to tear you down. She needs to learn to get her self-esteem from within or from doing for other people and not by controlling them.
