Set for a bench trial I was accused of battery domestic I have an attorney my husband advised he does not want to testify or further charge me

For many reasons, most going to witness intimidation, most D.A.'s have a "no drop" policy regardless of the wishes of the purported victim.  That said, your husband could call the prosecutor and request dismissal.  I would never counsel anyone to ignore a subpoena, but the fact remains that if witnesses do not show up for trial, usually the prosecution cannot proceed.
