I want to tell my daughter what to do
Fat, demanding, entitled, and unhappy, she wants to live vicariously through her thin daughter. Pathetic.
Get your father to drop the money from the wedding on an elopement, and invite him, and a few friends. Throw a nice party, have fun, you will barely remember your wedding day 10 years down the pike, but if you invest the money wisely, you will remember the early retirement for decades.
