I agree with the other posters that suggested you stop interacting with this person. She is only looking for you to entertain HER needs and simply cannot respect your needs other than to hand you constant criticisms about any positive you have in your life. As we experience life and interacting with different people, while a person we come across can be interesting and engaging somewhat, that person may not be someone we can grow in any good long term relationship with. It's really ok to distance when you start experiencing that challenge.
