Unless she has reported the accident to the Police, she has committed an offence by just leaving her details on your car. You have to GIVE your details, it is not good enough just to leave them. This is taken from Citizens Advice.
"The driver may also have to report the accident to a police officer or at a police station, in person, as soon as practicable and in any case within 24 hours. This duty arises whenever the driver has not given their name and address at the scene of the accident, whether or not they were asked to do so."
