About how much will my hospital bill cost for an ambulance ride?

I got into my first car accident today with my boyfriend. Went too fast around the corner and hit a tree, it was really scary. They called the ambulance and had to make sure my back was straight, we rode to the hospital, and they took a couple x-rays, checked to see if there was any pain and sent me home.

My boyfriend feels bad about this because he wanted me to go to his car club meeting with him. They drive fast around s-curves on the roads and he’s done it tons of time and have never been hurt. This was his first accident and he was crying and felt really terrible and said he’d offer to pay since it was his fault and that I barely make any money. Should I have him pay half of the cost?
