<human>: Can you condense the text into a few key points?

So I was SLOWLY backing out of my car spot about 5 days ago, which is about 6 spots away from a speed bump might I add, when a car hits my SIDE panel right by my right rear tire.

Now I couldn't see said car because of an S.U.V. parked next to me, which is why I was backing out so slowly. My insurance company is telling me that it is my fault because he was in the control lane and I was changing directions into his lane, yet I got maybe 1/4 of my car into the lane with he hit me.

For some reason I feel this isn't right at all, not only did he NOT slow down, he didn't even turn to the left so he could get past the back of my car....

If anyone has any experience with this type of problem I would REALLY love some assistance.
<bot>: Someone hit the side of my car while I was slowly backing out of my parking spot and my insurance wants me to cover his damage and pay for mine out of pocket.
