"My college girlfriend of five years dropped me like a hot potato when her IBM vice president father passed away and left her a huge amount of company stock and in addition valuable real estate. My girlfriend found out that she was an heiress when somebody in the middle the night dropped off the will of her late mother that left most of the family assets to her. 

 My girlfriend had nothing to do with her family because her father was an absolute bully, but the minute she got her hands on significant dough suddenly I was not good enough for her. The class separation, in particular when the woman is from a well-off family is an absolute brutal fact. 40 years later this experience still hurts."
