Fraud and mental torture

I got married in January this year in an arrange marriage setup. I didn’t felt much attachment in the courtship period. However, I thought that this might be his nature which might change after marriage. After a few week of marriage I observed continuous calls and messages from one of his male friend. The class were not normal, I mean 5-6 continuous missed calls which my husband didn’t picked. The same friend has blocked me from my husband’s WhatsApp and Instagram during the courtship period. One day when I went to sleep in the bedroom my husband was already there and left the room taking to his friend and came back after few hours. He used to continuously block unblock his friend on WhatsApp. Few days later I check his phone and read the message from his friend “humari relationship ka kya”. I was shocked. I asked him about the message. He got tears in his eyes and told me that his friend has bought some amount from him and he is just in contact to take that amount back. After 15 days we both came together to Pune. After one week his friend came to settle in Pune, mentioning he got the job. We were not having proper physical relationship since we got married. I thought he might take some time to open up. Like this 5-6 month passed. I observed several other scenarios related to his friend that were not usual. Like my husband went to his friend’s office trip in out car. My husband slept midnight at my birthday while he celebrated his friend’s birthday till 3 am and may more. I didn’t felt any emotional and physical attraction from his side. We used to have physical relationships once a month or so. I felt lack of touch. I used to do too much for him. Managing job, home and family relations as well. He use to sleep at the other end of the bed. I used to call him to sleep together, but his always used excuses. I started halving anxiety due to the stress. I shared everything with my sister in law. They assured me that they will have a talk with him once I reach my home for Rakshabandhan. After Rakshabandhan when I called her she told me to involve parents and that she is out. I told everything to my family. A family meeting got planned with both of us and out parent at their place. Once my family and me visited their place, they all started blaming me to rubbish things some of which I never did. Like I do not collect plates if in-laws after they are done with lunch. I get zoned out. I ask for roses. I do not work at their sister’s place and is always on phone. I try committing suicide. Which I tried, because of the stress and Handling situation alone. But I didn’t took any step. I just showed off. My mother told his mother about his physical issue and ask them to take medical help. Now my husband has left me Alone in Pune and again blaming me and trying to prove me mental for my anxiety. He is not accepting his physical weakness and trying to miss lead this matter by hiding the facts and raising false opinions. How can I move ahead legally?
