i got in a fight with my girlfriends brother and he pressed charges. he told the police that i fought him and his sister, my girlfriend, which wasn't true and the state picked up the case, charging me with domestic violence against her. she went to the DA and signed the paperwork saying that she didnt want to persue that issue because it wasn't true. when I went to court, the state dropped the assault charges against him but charged me with domestic violence against her. how and why is this possible in TX?
