If the accident is your fault then she's entitled to claim for all reasonable expenses to put her in a position as if the accident hadn't happened
including repairs, hire car etc.
But she is obliged to give you her insurance details. Contact the police saying she's refused and see what happens.
Stop dealing with her directly.
