I don't think so at all...perhaps she's looking to you to offer some kind of emotional support here for a decision or actions which clearly you don't want but she does...or thinks she does...
Its a tough set of circumstances to navigate your way through - offering "yourself" under some circumstances and not in others...but by doing so you are enforcing your boundaries without having to articulate them. Although when boundaries are spoken they seem to carry more force, by not doing so you are leaving space for your W to process them and perhaps in the long run that will create more room for thought on her part - there's less reason for her to consolidate her thought process and more room for doubt - so I think "good job!"
