Sorry to sound harsh, but although she is legally liable, but you could have prevented the incident by positioning yourself properly on the roadway. Opening doors are only one hazard -- the other is motorists pulling abruptly out of parking places or emerging from driveways, alleys, and side streets. Get out where you are visible. If the lane is less than about 20 feet wide (14 or 15 feet will suffice if there are no parked cars), claim it by riding right down the center or perhaps between the centerline and the right tire track, but never within 3, preferably 5, feet of the widest of the parked cars.
