leave someone to his or her resources

Let one rely on oneself to do what he or she likes or to get out of trouble. For example, Left to his own resources, my four-year-old might well turn the hose on the dog, or Refusing to pay for Lydia's traffic ticket, Dad insisted on leaving her to her resources.
