Someone rear-ended my car (not very serious), and he is willing to pay to repair it. Is it going to increase my insurance rates?

Hey guys,Today I was rear-ended by a car, and here is a photo of it: http://ift.tt/2rP4Q67 talked to that guy, and we decided not to call the insurance company. He left me the phone number and everything, and promised to pay to repair the car. He already paid me a little bit and asked me to call him if I need more money. My plan is to send my car to the bodyshop and see how much it is gonna be and send him the bill.It seems that if I send my car to the bodyshop, the bodyshop will either charge me with insurance or without insurance. So I wonder if it is going to affect my insurance rate a lot? Also, did I make a serious mistake of not letting the insurance company and police know about this accident even though it was very serious?Thanks! via /r/cars http://ift.tt/2t7L9tW
