If you'd do something for her just to ease some pressure/manipulate her in some way, obviously that wouldn't be appropriate. But, if not doing something would also be an attempt to define your worth by what you're doing vis-a-vis her (in this case, by withholding something from her as an act of withholding), would that be any better? What would respect both your core integrity and hers?
