I need gun license to save me and my family from a huge trouble

I want to purchase a gun for my safety as I was in a relationship with a girl for past ten years that is from 2007 to 2017, whoz father is a wanted criminal and a rowdy sheeter in Bangalore who is involved into many murder cases and kidnap cases. Even how her father is behind bars due to a kidnap case. I was been tortured and blackmailed by her quite often and reason for her to blackmail me was. She was having a affair with another guy which I came to know in the 2011. Only because I came to know her secrets she she insisted me to kill that guy which I was denying it. I was financially physically mentally abused by her and her mother . After few days she also tried to kill me but I some how escaped from that incident only because I was conscious and I knew that she will kill me. I was forced to live with because of her blackmails and threats now again she got caught with me having a affair with a guy where immediately informed my parents and I also informed her mom so that she will help me come out of this problem. I told her mom all which happened and I also told her that I don't want such kind of a girl I wana go away from her. But no. Her mom did not help me she started supporting her and even she started to threatening me telling that, I shouldn't tell all this to anyone if I do so then I will be murdered by her father. this is what she told me, then I told her that I will go to the commissioner office and tell all this to the commissioner that you guys are torturing and blackmailing me without no reason, then she told that she knows every one in the police department if do so I'll make you and your family face hell. But I know very clearly that they don't know anyone one as such and she is just trying to threaten me. So I told, that's ok you guys come to the commissioner office we will sort out everything there. That's when they got scared and let me go but I know they won't live me alive and I'm not scared of death only thing is that I don't Wana go living my mom alone my mom is a teacher and she is a very innocent lady and my father is secretary for Indian audit AGO we are from a very good background they are utilising our innocence and its not me. her brother had also done the same thing to a girl. She was been use by him and even she was been threatened by that lady the same way that girl is also from a very decent family. Will I get a gun to save my self and my family members from these monsters
