I not sure what you mean by claiming "good cause". Do you have a PFA? That would be your first priority. You also need to follow through with the criminal charges to ensure that he is punished. You really need to meet with an attorney as soon as possible to make sure that you are protected and that you understand your rights. If you are still in the house, you can call the abuse hotline and they will help you find a safe place to stay until you have a support order in place. Legal aid will file the PFA free of charge. Please don't wait.
My response is based solely on the limited information contained in the question. It is not meant to substitute your attorney's advice.
I also am confused what you mean by "good cause." Ultimately, you want to have a protection from abuse (PFA) against him, which can be done either by filing a PFA or through the terms of the criminal case for the simple assault. You want to protect yourself and show that you are the victim, and not allow him to turn it around on you. There is a high probability that if he was granted bail a condition of his bail will be to stay away from you. However, speak to a domestic violence specialist in your area to help you through this situation. You are not alone.
