Is it my fault?

I had an accident a few days ago on an Aldiparkplatz. I parked backwards from shearing to the right at once a car came from the left. She had a paint damage at the right door in front of the front left of the bumper so I was almost out of the gap. It was 19.50h the lady had it very quick to shop still fast when the accident occurred. I mean she drove on account of the haste carelessly. I brought the police this means because I had the greater duty to shoulder bl The driver also had a witness to take her exam so I assumed that I had no chance anyway so I accepted the warning .which is probably also a recognition of guilt. I feel however unfairly treated because I mean that she is also responsible. So now I have the insurance documents there must fill out questionnaires. Maybe someone knows and can advise me something? Not to forget I accepted the warning. I also have no desire for a I should like to ask the President-in-Office of the Council whether he is prepared to take part in this debate.
