How can I get domestic violence charges dropped?

Back in March, I was arrested for he said she said Domestic Violence charges which were assault 3 and disorderly conduct. There is no evidence that proved I did the charges against me, but because I live in Connecticut, the police have to arrest someone so they arrested me. I was able to get work with Family Services through the courts, but I don’t know if that was a good decision, because now I have to attend a group and do community service also. This has really been bothering me because these things are mandatory and there was no evidence to prove that the charges are true. I have been talking and working with the victim to get things straightened out and the victim wants to drop the charges but we don’t know if the prosecutor and the courts will allow. Please Please help.
