Can I get a restraining order?

You may certainly seek one form the courts. I hearing will determine if you get it or not. I can tell you that people have received them for less cause then you have stated but the final determination will be up to a judge. You would be better off asking this of a lawyer who practices in your state and has experience with family law or divorce law. You can petition for a restraining order on your own and there are many tools available on the internet to help you with it, there also may be local organizations that ist women in abusive relationships that could offer free help. My advice is to ask for legal advice from an attorney in your area because laws vary slightly from state to state and a local expert will have the specific information you need.
