I warned you that this would happen. They courted you with flattery, favors, and gifts that you could have easily bought for yourself.
Now you're out millions, and they have shifted operations overseas.
You should have insisted on a written contract; but no, you said that they were too nice to not be trusted; and besides, who was I to give you advice? Just another (now former) employee.
Good luck trying to get your money, your house, and your family back.
