International marriage

Hi there, I came to the uk from India after getting married in 2016 with my husband. My husband is a resident here but I am on spouse visa. I suffered domestic violence and reported it to the police. Now we are living separately. I have few questions if you can help me with. 1. My husband and I born, grew up and married in India, now he has Indefinite leave to remain in the U.K., can we divorce in India or in the uk only? 2. I am currently having an Indian passport, he took me to this country after marriage. After coming to the U.K. he treated me badly and I reported it to the police. I also gave him a chance by dropping the allegations but then he didn’t turn up and I re raised the case because I didn’t feel safe. He made me move out from the property by saying he lost his job from the university so he can’t rent the property anymore because it was the university accommodation. He deserted me in the foreign country, what is the best thing to do in my case? 3. We are separated (not legally) since 1 September 2020, he wrote an email to me saying I took some of his stuff which isn’t true. What should I do ? 4. It was a case of Domestic violence so should I reply to his email or not? 5. He earns a lot more than me, I do a temporary job which is very low salaried. should I be eligible to get alimony or maintenance ? 6. My father gave money to his father as a gift which was around 11 k by check and 5k by cash. My father also spent lots of my on wedding ceremony as well. Will be eligible to get the money back? 7. He and his family is after me and my family. They can try to kill us. What shall we do in that case? 8. I will not be able to afford legal expense, what should I do ? 9. My husband and his family is taking this matter as his reputation and they will try to ruin me personally, financially and professionally. What he and his family can do ? 10. He destroyed my physical and mental health and now days, I am on antidepressant drugs. It is affecting my work as well. Can I get any compensation for that? 11. I need to study in this country but don’t have enough money, am I eligible to ask him to pay for my fee? 12. I have seen him sending emails to a lady who used to be his girlfriend and saw him seeing her in the city. So I believe he cheated on me. But he refused it. I have some screenshots of his communication with her even after marriage. 13. He used to say he will transfer all his money to his father/brother in India if divorce happen and he won’t give me anything. I will have to give him money but I don’t have enough money how can I give money to him. 14. I have my jewellery which my parents gave me in my joint account locker in India, can I get that jewellery back? 15. Am I eligible for free legal advice. What is the procedure? 16. My husband and his family members demanded for dowry and tourcherd me for that. My father had given an application to the Indian police in this regard.
