Did you have witnesses ?
As you describe it, then it sounds to be her fault as she collided with you as you tried to pass what seemed to be a car just parked. But there is always the result of two accounts being read and a decision come to.
As mentioned it is cheaper for the companies to come to an agreement early than it is to argue the case, but if they say you are not to blame you can insist. My last accident was when I was hit in the back left wheel arch by a car that I didn't see because they were apparently driving in a lane that didn't exist to my left ! I insisted I was 100% blameless and whatever the insurance companies decided amongst themselves there showed no penalty to me by the time they'd finished.
