No. The right way of "stopping" your husband from getting his I-485 approved is to simply send a letter to the USCIS District office where the AOS is currently pending at and where you and your husband are going to be scheduled to be interviewed .
Enter you'll send USCIS should simply state (without offering any explanation or justification) that you hereby withdraw the Form I-130 Petition for Alien Relative you recently filed on his behalf, effective immediately.
Address the letter to the district director him/herself.
Make sure to send the letter with certified mail, return receipt requested and keep a copy for yourself. Better yet, you can also schedule an INFOPASS appointment at the district office, where you present a other original withdrawal letter and make sure it gets into the AOS file. Your soon to be ex husband's AOS will then collapse like a "house of cards". He will have no status left and will be asked to depart.
Being a man and not a woman, any VAWA case his immigration attorney may want to bring will fail, for unlike what is in the books, USCIS hardly ever approved a VAWA case filed by a man..
