Awkward first date hug

I need some advice, I went on an amazing date with a guy I've had a crush on for almost 2 years now! We had a good time considering where I live, there is absolutely nothing to do! At the end of the night, he walked me to my door, he went in for a low back hug so I put my arms around his neck, he then picked me up and popped my back! I didn't know what to do or say! He started to walk backwards and kind of sheltered himself behind the car and asked me if I worked the next day? (We work together) What do y'all think?
