If I was charged with domestic violence and the accuser doesn't come to court what are the possible Outcomes of this and what should I do

The chances that you will be prosecuted is speculative.  From what you shared -- and I am sorry you are going through this -- it sounds like the District Attorney does not care that the alleged victim is not showing up and under section 1108 of the Evidence Code, the DA might be trying to use that prior conduct against you in this case?  Actor Mel Gibson was convicted of DV despite his girlfriend/fiance not showing up to court in Orange County.  In the end, the answer to your question really depends upon what the judge does and what your lawyer does.  You might want to hire a lawyer you feel knows what s/he is doing and has your trust that you are being defended in the best way possible.
