The worst thing I [m] ever did [f]

When I was in high school I had an on/off relationship with a girl named Jessica. She was a very pretty, athletic girl from a wealthy family. Think college soccer player; slim with an ass you could bounce a quarter off of. For visual I was 5’9″, 160 lbs, around 9% bf, shaggy brown hair, and 7″ for those that care. Her family loved and trusted me and we still talk occasionally to this day. The problem was Jessica was absolutely crazy. She strung me along, fought about everything and overall was a drain on me life. When I was 19 she had broken up with me in a particular fit of crazy and burned all the belongings she had of mine. About a month after that her family offered me a good bit of money plus access to their sweet house and liquor cabinet for a week while they were on vacation to housesit.
