How can I demand financial support from my husband?

On July 7, 2024, I got married. From the beginning, we have misunderstandings because of marriage arrangements. He has not shown love and affection to me. He spoke rudely with me. After 5 days of marriage, he told me that I was not fit for us. After one week, his brother scolded him because he treated me without respect and he asked me to separate. After that, our family asked for marriage registration, but he said that he had a lot of work so not able to register for marriage now. But our family asked one more time about registration. So he got angered and one day he cut his hand with a blade because he told me that he lost his job. It became a family problem. After one month he went to Abu Dhabi, he was not ready to speak with me and avoided me. Finally, he was not ready to live with me and asked for separation. Not even give a single rupee for my survival and blackmailing if anyone is convinced that he will commit suicide. Still, now he has not yet answered my phone calls and messages.
