It doesn’t work that way. The prosecution of a case is the responsibility of the Crown Attorney and it is only the Crown Attorney who can decide to “drop” a case. In many cases the Crown will still prosecute a case even if they believe the complainant does not wish the charges to go any further. If your spouse wishes to recant some or all of the story she gave, you should speak with a lawyer to discuss the potential impact of this on the charges against you.
