I am so sorry to hear about your situation. My husband did something similar with a company he left. He changed jobs right before his stock vested. About 2 years later the company sold, and we found out about all of the money we lost-enough to pay off the house, send the kids to college, and set us up well for retirement. It made us sick. I feel your pain.
Thank you so much for sharing that. It does help to hear that you are not alone. I am slowly finding my peace with this. Money isn't everything. This was just the kick in the pants I needed to get myself in gear. A very very hard but valuable lesson.
