I want to drop charges on my ex for assaulting me but ive already done a.deposition? how can i make this go away?

This question was posted under the wrong practice area. I am reclassifying this to the criminal defense category so that lawyers knowledgeable in that area can respond.

Cooperate with the defense attorney on how you may be helpful to their case.

If you are the victim of an act of DV then the State's job is to elicit your testimony and prosecute. In Florida the State Attorney is empowered to bring criminal charges to bear on behalf of all of the people of the State, the victim being only one of those millions of people (albeit usually an important one to the success of their case). If you do not wish to cooperate with the State then you are entitled to have them consider your wishes. In Florida victims of crimes have rights, both constitutional (s. 16, Art. I of the Florida's State Constitution) and by statute. If you want to increase your odds at having the State pursue your interests then you can hire your own criminal defense lawyer to serve as your Victim's Right's Advocate. Again, no one can control what the State does on behalf of the people, but you will increase your odds at achieving a favorable outcome if you have an effective victim's rights advocate pursuing your agenda. Many criminal defense lawyers serve as effective victim's rights advocates. Wishing you luck and hoping that I have been helpful in answering your question.

The State has total discretion in whether or not to "drop" the case. Contrary to popular belief, the victim is not able to directly control this. Writing a notarized letter to the State which articulates your position and assures the State that you are not afraid of the Defendant will usually be effective. Cooperate with defense counsel and even consider hiring your own attorney to represent your interests in the matter.
