I lied to ins. co. and police and said I was driver in accident, but it really was my unlicensed ex gf--is this fraud since I recev''d a check?

My ex girlfriend got into an auto accident last February when she lost control of my vehicle and crashed into a ramp wall coming off of an interstate. No one was hurt, as she had 3 other passengers in the car with her. She got a ride to my home two or three minutes down the road and told me what happened, and I told her and her nieces+nephew to stay at my house and not return to the scene. Problem is, it was MY minivan and I had full coverage--but I told my insurance co. that I was driving, and everyone else were the passengers. She also had no license at the time from a DUI conviction, and I knew this, but let her drive anyway.I lied to the state police as well, when they came later that night, and even though the cops did not speak to her, I coached her on what to tell my ins. co. They ended up paying for my rental and cutting me a $10,000 check for the loss. Ins. co doesn''t seem to care, but I think the Atty. Gen office DOES. My ex reported me to fraud bureau in PA. Am I in trouble?
