My child father was just arrested for domestic violence

As the title says, I just had to have the father of my children arrested for domestic violence against me. We have been living together even though separated for the last month because we have a son who has medical needs and splitting households isn't as easy. We have been in the process of splitting households but I'm waiting for a caregiver for our son. It got to a point where I had to call the cops today and have him arrested. I'm not sure what to do because the car that I have is in his name because I didn't have good enough credit. I'm wondering if anyone has any information on this?
