Turn the matter over to your insurer immediately. Cooperate with your insurer. If you are sued, you will be provided counsel as part of your cooperative agreement with your insurer.
And next time, do not say anything at the scene about fault.
I agree with the sentiments of the previous poster. Never admit fault!
I would contact your insurance company. They will be in the best position to advise you.
Best of luck.
If you don't have insurance and you refuse to pay, a lawsuit will be filed against you. At that point you can present your side of the case. If you have insurance turn it over to them.
