Husband abuse

My husband working in Qatar. I came here 6 months before after 3 years of life in India with 2 small kids alone in a home. My elder daughter is 9 years old. The younger is a 3-year-old boy. My husband is a narcissistic person. He is always on mobile, laptop, or TV. He has no communication with me. I doubt he has another relationship because he has no attachment to me. He sleeps separately after coming to Qatar. He is always hiding everything from me. 3 years before he was not like this. He got a job 3 years before. I and my daughter were in India for the delivery of my son. I have a job in India that I am doing remotely. I have to manage the kids, work, and the kitchen. My husband does not help me. Yet he is not ready to spend even for my basic needs in Qatar. He is telling spend my salary. When we were in India, I had to spend all expenses for 9 months, as my husband did not give me money. Now in Qatar, I cannot manage because cannot spend rupees in Riyal. Moreover, he is not helping me at all in doing work. He is treating me just as a servant looking after the kids. After coming here, he is telling 'get lost from here' if I ask anything or try to communicate with him. He is physically torturing me a lot in front of my kids. Last week he went outside at midnight without telling anything with his bag in his car. After 2 nights he came back. Nobody know where he was. Now I can't feel him as my husband. I dnt talk to him unnecessarily after this incident. I do my duties very well at home now also. Yet he is angry when I eat food and throws my plate when I was eating food. Also, he physically tortured me. He is telling got to the police, I am ready to go to jail. He is confident he can escape as I am not smart like him. What will I do now?
