Hi I have had the same issuse and you can not withdraw your statement only make a second to say why you would like to withdraw, you can tell the prosecution you do not support the prosecuting of your husband but it is totally down to the CPS as to weather they have enough evidence to continue a prosecution and get a conviction. You can also ask an officer to write a victim statement which the judge will see, how your life has changed and what effect the incident had on you if it goes to court. You may need to hang on to see what he is being charged with if he is and what pleas he will put in as if it goes to a trial the CPS will more than likely call you to give evidence and can use your first statement. Also withdrawing can make his case look bad as they may take it that you are intimidated by him. Good luck.
