My question involves a marriage in the state of:Mississippi

my wife had made a threat to me on tape as well as in writing that if i did not sign the divorce papers she would have me thrown in jail for stealing cash?? i declined and told her i would not be blackmailed...she had me arrested the next day....do i need to be found not guilty before filing charges against her...Is this considered Blackmail or extortion??? it has cost me allot of money as well as trouble with my job for being arrested....i want to file charges back on her..what do i charge her with??
