No that will not hold up in court. He is trying to scare you. You will have FAR more evidence at what an abusive bully this man is and no judge would say "oh you were right to beat the crap out of her she IS a whore..case dismissed!". I don't think so. Don't listen to him he is LYING. HE is the one who is going to get in trouble he is not proof of you doing anything he is the one who is abusing you, harassing you, threatening you AND HE IS THE CHEATER HERE. What a dumba$$
