My husband have left me for his parents

I’m married for 1yr 2month. I had problem with my in laws so me n my husband shifted to house near by to my in laws place. Initially when this problem happened I was at my moms place for 2month then I could nt stay way from my husband so u started fighting n got separate house. He agreed for it. During tat 2 month I stayed in my parents place his parents never called and asked me to come back. We had problem from long it was between me n my husband. I use to fight with him go to my moms place n come back thinking this time things ll change. But never happened my In laws were always same. They never fought with me but they did silent torcher. They never spoke to me. Never use allow me watch wat I want. No help in kitchen. Even if I was sick no 1 took care of me. Even involved me in there family talk. Make faces n tell again n again my son has changed a lot after getting married to u. If he doesn’t attend family function they ll create big mess as if I have stopped him. It was love marriage. I could nt take there behaviour so I left but they never stopped me. Before leaving I tried speaking to my mom in law bout my problem but she misunderstood n called many people at home including my parents. So I felt bad why did we call so many people which could be sort between us why so many people came. I left home. But they never called me back. So I requested my husband to shift. I fought for it as they were not ready to shift. Then we shifted n stayed for 2 month there. My husband was least happy at home. Nt involving always absent type. He use to tempt me to fight with him. Lie n go to his mom place as if I have stopped him. Swear I never stopped him from going to his moms place. Once I fight I just told cos his mom had blocked me on wats app. Telling ur parents want only u nt me. U also don’t go. Just once. He felt offensive. He has left me now telling I can’t leave my parents they r old. Actually his parents age is 55 max I think. Fine I’m ok with him taking care of his parents but at same time he should even take care of me. He left me all alone at home . Doesn’t even come to see me if I’m sick. If we talk bout this he talk law n tell it’s illegal to leave parents it’s seems I can’t leave them. I am not asking him to take care of his parents and pay rent or do anything but leaving me n going like this also not correct right? He keep threatening me telling it’s illegal to leave Parents but he s ok leaving me. But why should I leave him. I fought with my parents to get married to him I can’t give up on my marriage. What can I do? I want him back in life. What is possible solution legally. Is what he is telling is correct then what bout me? What should I do? What’s his responsibility towards me? I don’t want money but I just wanna know what he is doing is correct to leave me alone and go like this after marriage?
