HELP NEED URGENT ADVICE

Okay i need advice. I filed charges against my bf for domestic violence cause when we broke up he punched my microwave and a few small other things. Bottom line is then he tried to commit suicide and we learned he has mental illness/emotional disorders. He pretty much had a psychotic break. We worked things out. He’s never threatened me, caused any physical harm to me, or anything like that. I just need some advice on what to say to the prosecutor to drop charges? He has no priors and the charge is a misdemeanor. I really made a mistake going to the police because they talked me into charges when i wasn’t sure that was what i wanted to do. My bf needed help. Not jail. I have an appointment tomorrow morning before his arraignment to speak with the prosecutor
