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?
It's a feeling...not a tactic.
But to address your point, I actually did get her something. The act of *not* getting her something is a resentful stance which I don't want to partake though I do feel a little resentful. Anyway, I'm really trying hard to "act" the part of a H in love with his W. Hopefully the behavior will reinforce those true feelings. Behaviors and feelings seem to feed off one-another and in no particular order...I'm behaving like the man I want to be.
