How do I drop charges without being picked up by Commonwealth?

My boyfriend and I had an altercation the other night. He called cops to have me "escourted" out... and they figured out it was a domestic dispute... they said one of us had to be arrested... and it ended up being him and he was the one charged. I gave a written statement. How do I have the charges dropped without commonwealth picking them up?? I do not want him to sit in jail over this. He did get No bond by magistrate and has video arraignment tomorrow. More than likely will be no bond again he is a flight risk.. by the time we go to court he will probably get time served... This happened in state of virginia. thanks for any input
