Just as a heads up, HP, the more you don't respond to her manipulation, the more likely it is that she'll become frustrated and retaliate. That isn't to say you aren't doing the right and best thing for you and your S (I believe you are), it's just a warning so that you do not get blindsided with seemingly 'off' behavior of hers as control shifts out of her hands and into a more balanced state between the two of you. People don't like losing control, especially WAWs, and even when they have a disproportionate amount of it.
