leave (one) to (one's) (own) resources
To leave one unsupervised or uncontrolled; to allow one to do as one pleases; to allow one to rely on oneself, without any help or interference. I'm going to leave you to your own resources and see what you come up with without my input. It's amazing how some kids can really thrive when you leave them to their resources, while others will be completely helpless.
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.
