Sorry for the delay. YOur reply came through after midnight where I am located, and I had turned off my computer for the night by then.
If you are the alleged victim of the crime, you can submit an affidavit of non-prosecution. However, once the state has become involved, the case does not belong to you anymore but to the prosecutor. He or she is free to go forward with the matter, even over your objection to go forward. YOu can be subpoenaed and compelled to testify against your husband, even if you don't want to, or face contempt charges for ignoring the court order.
You should make your feelings about this case known to the prosecutor if you don't want to go forward, either by an affidavit or by making an appointment with the prosecutor and telling him or her in person. Either way, it's important that as a result of your affidavit or visit you convince him or her that you will not be at risk of harm if the charges are dropped and the protective order lifted. Also it's important that the prosecutor know that you're coming forward to drop the charges of your own free will and not because your spouse has bullied you into it.
If the prosecutor insists on going forward after you've made your intentions clear, talk to your husband's lawyer and let him or her know that you've been trying to drop but the prosecutor won't let you. He'll take it from there. Ask him what you can do to help.
In my experience, once the defense attorney and the alleged victim of the crime start holding hands and pressuring the prosecutor to dismiss the case, something favorable to all parties can typically be worked out.
Best of luck with the case!
