You can't file charges only the DA can do that but you can make a complaint. If it happened in California then it must be reported there.
This is just my opinion and you assume the risk because I am not promising it is completely accurate.
Although the DA decides when to file criminal charges, you decide if civil charges are appropriate. Had you sought protection in 2009 when the abuse happened a restraining order may have been granted. Why did you wait so long to pursue a restraining order against your ex husband? Too much time has lapsed between the abuse and the time of filing for a restraining order. The judge needs recent evidence of abuse to grant a restraining order.
