If my accusor on a grand larceny charge doesn't show up for court will my case be dismissed?

I was with a guy I used to talk to last October and we drove from our hometown Spartanburg SC to Columbia SC and ended up getting a hotel room. Well we got into a heated argument and I asked him to take me home and he refused. At that point I felt trapped and I had no money. Later that evening I asked him if I could drive his car to store for some cigarettes and he agreed and handed me keys to his car. Well I ended up driving myself back home and called him and told him his car was left at a Wal-Mart parking lot n keys were in dash. I never heard anything else from him. Well just recently I got picked up on warrant from Columbia for a grand larceny charge stating I took his car without permission . Apparently he never got his car back bc someone stole it from parking lot after I left it. They say they have video of me getting into his car at hotel the night I left. But I didn't exactly steal it bc he gave me permission. There are no witnesses bc it was only me and him.
