Good advice from your L. Better to have it documented and agreed to than for her to start to use it as a way to poke at you. Obviously you would never use your D against your W, but based on the rest of your sitch I can't guarantee that your W will not at some point, especially, as you point out, as she starts thinking more and more you have this imaginary OW.

I'd follow that advice if I were you.
