stop talking to the women if she keeps phoneing you its classed as harrasement, have you admitted to hitting her?
shouldnt have said a word to her at the scene should have swapped details and drove off. thats all you are required to do.

i had sum muppet jump a red light i went in the side of him he pulled over admitted it and said he would pay cash to get my car sorted and swapped details.. then i spoke to him and he said he was getting onto the insurance company so i contacted my insurance he
said i had hit him from a side turning but i had a witness who just so happened to work for churchill car insurance who helped me with wat to do and stuff told me to stop foneing him or he could have me done for harrasement. i reported to the police straight away then, in the end his insurance company was saying i pulled out on him but the police proscuted him for jumping a red light .

even if her car did roll back onto yours it would be your fault still for being to close.
