Nri divorice

Hello, Last year in February i came to India and got married in Punjab. However, after i got married my husband was acting weird right after i did "Fere". Him and relatives did not wanted me to show where he lives and neither wanted to introduce me as his wife to anyone. When I pressured them that i want to see where he live, since i started doubting something is fishy. They took me to his house for 10 mins and told me to hide myself and walk in their house, so no one in the neighborhood can find out he is married. Come on usually in India wedding is so fun and that's what i thought its going to be for me but it was nothing like i expected. They dint do any rituals after the wedding. And my husband side of family told me once he gets Visa for USA only then will inform in public about our wedding. "I was like No way" this is not right. I spent two days with him and flew back. We did not bond in any way. I returned back to US and was i a shock of everything that happened with me and decided to talk to him over the phone for few month and learn about his character. When i used to talk to him over the phone, he used make fun of my weight and always to put me down all the time. (Well i am a fitness freak and a hiker) but still he cracked jokes about me all the time. He had anger issues and used to get angry very quickly. Well after that i decided i am not going to file his US Visa neither i want to register my marriage in US. However i did register in India. Now Finally a year after my husband in India wants a divorce. I am very happy to give him divorce, since he would had made my life miserable. His relatives were threatening my relatives in India that he is going to do something bad to me, so i don't want to go to India to sign any papers. I have asked them to email it to me any documents or do a video call. How can i get divorce in India without coming to India. My whole family is in US and i only have cousins and extended family in India. Please email me. Thanks and appreciate your response.
