I had a very bad past where I was in physical relationship with like 10 guys that was due to the earlier relationship I had where I was being used financially and physically that hurt and me and I got really f***** up in my mind so I started dating guys just for physical relationship then the last guy I was in relationship with I got pregnant with a baby and I aborted it because I did not want to have a future with him and also I did not have confidence to grow that baby. then 4 months later I met my husband I fell in love with him at the first meet and we had physical thing at the very first meet. during the second meet he read the group chat between me and my friends where we spoke bad words ,my husband was not okay with that and he was really feeling bad about it and he started to talk about our break up.I was waiting for my final yr results when I met him soon I got my result then I have to start my internship my husband paid 5 lacs rupees for me but he was anxious that I will be with the friends who I was talking bad words with in college and he wanted to have a breakup and he fighted everyday with that reason .I promised him that I will not be that person anymore and I won't talk to my friends. one day I helped my friend with work for which my husband got angry and he wanted to have a break up and he started to talk about the last guy which I said that he was a friend before and I don't talk to him anymore then he raised question about him and then I told him that I was having a Friends with benefit relationship with him, then things got bitter and he seriously wants break up this time,.everyday he talks to me about that and fights with me I stop going to college .one day I made a suicide attempt and then 2 days after he started talking to me normally. soon again he started asking all those questions about the last guy I have been with, he asked very minute questions about the day and dates and he fighted with me everyday for that. there is a friend of mine who knows everything about my past ,in all these chaos,things got bitter between me and her and we stop talking. one day my husband talked to her and he asked everything about me and he got to know all about my past and he said that he took all the history of my chats ,apps and photos and asked me questions repeatedly and I told him everything completely without hiding anything. then things got messed up. I was really distressed, then my family got involved and things got very bitter, he told everything about my past to my mother. one day, they made me stop talking to him. he sent message to my sister in law and brother about my past, then my mother went to my husband's sister and told her that my husband is making a big mess not allowing me to go to internship and he has all our intimate pictures then things got Messed up more and he stopped talking to me. he was just asking me the 5 lakhs rupees he paid for me and then we stopped talking for about a week, I turned completely insane during that period and I sent him txt that I am not able to live without him .then we started talking, few days after he was okay with me going to the college then again he started fighting he was not ok with me to go to college. then we decided to get register married which a day later he denied.then I ran away from my house to him ,he received me and I was with him for 3 months we lived together for 3 months during which period he spoke really bad of me because of my past which I endured because I was really feeling guilty of my past and I thought I deserved it. he was asking even all those small personal things and he hurted me so much with his words which was mere verbal abuse ,meanwhile I got pregnant then he introduced me to his family and then we got married registered in front of our family. it was an inter religious marriage. all this time he controls me for every little thing like I should do this and I should do that which I did not take seriously then. now everything got secured my mom wanted me to complete my degree in my hometown because I was not able to complete it anywhere else but my husband was not ok with me going to my hometown to complete my degree because of my past things. I have financial things to take care of because of the money spent for my degree so I was thinking to make a deal either to finish my degree or I wanted my husband to give back the money that was spent for my degree because he said so but then later he started to humiliate my family for expecting money from me and he told that they we just see me as an investment to earn back the money they spent on me. But my family wanted me to complete the degree at the first place.this created a lot of arguments between me and him . Finally,one day my mom approach his family and she wanted me to come with her to complete my degree but my husband was not ok with it and I was still supporting him my mom told that she will die if I didn't complete my degree because that was all that she dreamed for me her entire life. then they sent me to my hometown with my mom to complete my degree. after coming here my husband did not talk to me for 2 days, then he texted me that he does not want to live with me. he told that I and my family were being fake and we were using him and we broke him into pieces and made him go through the pain which he did not deserve. I got really emotional and I told him that I wanted to go back to him. he told me that he will take me to him the next day that he will book a bus for me to reach back to him but he did not contact me the next day .then a day later he started making arguments again this time, he said that he wanted divorce from me because he cannot have a life with me .he told that he does not want to be in my life and our child's life, if I want he can give financial support for my child's growth. I denied the money and I told him that I am not willing for a divorce unless or otherwise he wants to marry another girl then he 3 hrs later, he sent a letter of intent to divorce and I did not reply for it .what should I do now?
