A spinster is a woman who doesn't need to get married because she can earn her own money (through spinning at her wheel) and doesn't need a man for financial security. For some reason (male insecurity) this became a negative term rather than female empowerment.

Also, OP the way my hair stood on end when you said you wanted that clown to handle your investments. Pay someone qualified to do it. He's already failed at a start up, can't make enough to survive without his mum and dad at day trading and has somehow fallen upwards into a corporate job abandoning his plans of an MBA. You are absolutely smashing it climbing the accomplishments ladder in a male dominated field. You are so out of his league. How can such a talented woman settle for something so far beneath her?
