What should I do now. Please help

Hello respected all advocates I am Kunal chandhok R/O new delhi. Although I never thought to get into all our laws and take this step still it's life. No one knows what you will be forced to do with time. I have my girlfriend where we love each other and blindly trust on each other. What has happened now is my girl decided to make her parents meet a guy 7 years back to make them aware of their long term marriage plans. Now slowly slowly she noticed that the guy is not right. He is indulged into all such activities which a girl will never expect to see in her husband. At that time her parents told all their relatives about this and all agreed with their relation. Now that guy is like a great guy in eyes of everyone. My girl knows the truth and no one is ready to listen to her saying why didn't you think before. Now we both want to marry each other. Forcefully her ring ceremony has been done with that guy 2 weeks back. And now we both want to get married in eyes of law so that we can show to everyone with papers that we are married. I know nothing can be done here. We need to take a step to run away from here and get married in some other state. I am planning to get married in arya samaj Mandir and then instantly court marriage. Now I even have a risk of getting beaten by her father as he has said this that he will kill me if her daughter marries me . We both are sure about each other. And we want to married. So please help in this. I want to know how much time it takes in these both marriages and after that how will I keep myself safe from her parents and relatives. Please help me. Regards, Kunal
