I brought flowers and Paris flight tickets to the office to surprise my husband for Valentine’s Day. But the entire company was celebrating his engagement to the female CEO. My husband kissed her, then held up a diamond ring while the crowd cheered. I turned around and walked away. I immediately canceled the trip. Froze all joint accounts. And withdrew my 83% share from the company—worth 558 million. Thirty minutes later, my phone showed 152 missed calls. Then my doorbell rang.
