This is a specific situation that would be difficult to answer in a single comment. There are a few scenarios where your girlfriend might be justified, but generally she would have to give you notice before evicting you in such a matter. Unfortunately, the solution is not a fast process. You should contact an attorney in your area for help. If you cannot afford one, Legal Aid of Western Missouri has information for people in your situation. http://lawmo.org/pro-se-tenant-defense-documents/
