Divorce from a violent person

I want to file for divorce. But before that, I will need to leave for another state. My husband is a very cruel man, I am afraid that he might do something to me when he finds out about my plans. Therefore, I saved up some money, check into a hotel in another state, and file it remotely for divorce using this service https://paonlinedivorce.com. I will have a good time in two weeks, he is going to leave with his brother for the Christmas holidays and will be with him for a few days. I will have time to organize everything. Is there something in my plan that I am not satisfied with? Can someone help me with some advice?
