I lived with a girl for 4 years. She was going to school getting her masters and working part time waitressing. I paid for absolutely everything during the relationship as she was supposed to be a broke student. I caught her cheating on me and dumped her. I soon found out she had some large grants to pay for school, her mother was giving her money to go to school and she made almost as much money as I did. After 4 years I had about $500 to my name and she had saved over $40,000. Good times.
