Husband has abandoned me and now his family is asking for divorce

I got engaged and registered marriage with my husband last year in December. It was an arranged marriage and everything happened within 10 days of meeting each other as he had to leave for abroad in December itself. Everything was great initially but as time passed, I realized that his friends were more important to him than our marriage and I also mentioned my problem of him being over-friendly with his female friends. I understand that friends hold great significance in one's life but after marriage, it is important to keep some healthy boundaries with them. However, even after bringing this up a few times, he said that he couldn't change this and one of his friend's wife commented on his Instagram picture that he is looking handsome with some kiss emojis. I objected to this and we kind of fought. He ignored my calls and messages for a couple of days and then called me and said that he wanted a divorce and then blocked me. His family has been pressurizing me and my family for divorce and also my husband shared my private pictures and our private conversation with his family. We got physical after our engagement party and now I feel that he took advantage of me. I don't want a divorce and want to go back to him but he is hellbent on getting a divorce and wants it to be mutual. He is not here in India. I don't have any way to contact him and the only option I know is to File an FIR. Any advice will be appreciated. Thank you.
