Well this is what happens when you marry someone obsessed with their appearance. Narcissists gonna do what narcissists gonna do.

Make her clothing fund go to a therapist. She’s got issues that need addressing. Before the next shopping trip.

That's an easy fix, if you're willing to compliment her on every new piece of clothing she buys. Even if you accidentally compliment her on a piece of clothing she already had, it's still a win-win.

Is she donating or selling/returning it? Makes a slight difference in the "thousands of dollars" you're losing.

My question what did you do and why do you not compliment her? Woman like compliments
