You at the very least should be fully researched, and have consulted with a L to know your options and what you want. This doesn't need to be discussed with your W. Since she wants the D she should be the one driving it not you. If she doesn't want to drive then go about your merry business unless you want to file. However, from my perspective if you know what you want, and if this goes to D then you can gently coach her turn left or turn right. I see it as damage control.
