<prompt> Human: Im very upset with my girlfriend and her brother right now. He loaned 10,000 from me, January of last year, and promised to pay at the end of the year. Its 2018 now and I havent gotten any penny back yet. I agreed to let him borrow that much money because of my girlfriends assurance. She said it will really help him turn his life around and I believed her. Some business investment of sort.I reminded her of her brothers loan but shes giving me a fit whenever I bring it up. I may or may not have used some unrefined words when we argued about the issue. I cant help it though. Not only did I stop hearing from him mid 2017, I also just recently found out from someone else that he used the money to join this stupid foreign bride social event instead of that investment thing he initially told me. I tried calling him, emailing him, and other means but hes not replying. What do I do now?  <response>: 1. He borrowed money or took a loan of 10k from you. You lent or loaned it to him.2. Judge Judy was created for exactly this situation.
