Legal advice

My mother was a teacher in a govt school in Bhutan and my father is in GREF. In a recent argument regarding monthly expenses in the house, my father stated that he intentionally made my mom to quit the job as he wanted to teach me and my mom a lesson. He said not to touch his earnings, if we were to meet the monthly expenses, we should earn by ourselves - my mother is still taking home tuitions. When I competed my graduation, I was placed in a number of reputed companies and he didn't allow me to join any of them. I always wanted to study abroad for which my mother paid for my IELTS coaching from her savings, and when I was prepared for the exam, my father said he's not ready to pay for the expenses. He is narcissist and has never been there for me as a father or for my mother as her husband. He and his family has been harassing her physically and emotionally since the past 26 years. She tolerated all of that for me, because he himself told her in the initial stages of their marriage that "we should stay together for our daughter". I am 23 years old now, and it was a month ago that he raised her hands on my mom again. It was that day that I questioned him about his role in my life. My paternal grandmother has been spreading abusive and irrelevant rumours about me and my mother in the locality we live in. We have always tried to convey the problems with him, but in the end he is always against us. Me and my mother have spend around 11 years in Bhutan just with what my mother was earning, he had no role in it and now that she's unemployed he's harassing both of us. Both of us are at a stage where we cannot take it any further. We don't know how we should move further, as we do not have much money as well as time in our hand to spend if we move legally.
