You were backing out of your driveway the other day and your neighbor was backing out at the same time you ended up backing into each other you were both going to go East?

I live on the south side of the street she lives on the north. Our driveways are even with each other. When we bumped into each other my driveside bumper and her front passanger door were dented. Who is more at fault. She was running late for work and did not want too call the police and now she is saying I hit her and it is my fault. Initailly she stated the same as me that neither of us were paying attention to behind us only too oncoming traffic.
