Hello,
Depending on the nature of the charge, you will not be able to interfere with the state prosecuting someone.
Generally your influence is limited to if you have filed a complaint. This however DOES NOT include domestic abuse issues. A domestic abuse charge can not be revoked by the victim in most jurisdictions.
The DA's office is responsible for looking at the information presented, and seeing if there is enough evidence of a crime to warrant a prosecution.
If this does not address your concerns please let me know. More detail would help in providing a specific answer for you.
