You were cited for spousal battery 3 months ago went to court and was told the DA would contact you if the case was going forward you were cited and released and want charges dropped?
From what you say, the case is now in the prosecutors hands. You must wait and see what action (if any) is contemplated by the prosecutor's office. Spousal Battery and Domestic Violence offenses are handled a little differently than 'routine' assault cases. If you don't hear anything from the DA's office contact them and ask what the disposition of the case is. You have every right to do so - you want to know if there's a case hanging over your head, or not.
