I canceled my ex-mother-in-law’s credit card the moment the divorce was finalized—and when my ex called, furious, I finally said everything I had kept bottled up for years. “She’s your mother, not mine. If she still wants quilted Chanel bags from Fifth Avenue, figure out how to pay for them yourself.”

I worked late, but not because I was trying to keep someone else’s fantasy alive. I worked because I was building something that was mine.
