Minimum months to file a divorce for newly married couple

Hi, I got married 4 months before, There is no such husband nd wife relationship between us, he is from tamilnadu nd iam from Andhrapradesh, His Father is a Friend for my family from past 15 years, He is a paster so used to come to our house for conducting prayer, No mother-in-law as she is passed away,Marriage was conducted in church, we are hindus and they are christians, so he asked our family to give me to his son nd so that marriage happened. before marriage as a friend my husband is fine with me and with my family members, After marriage only we came to know he is so arrogant and fighting with me always for all even silly things, That I have to act according to his wish and his father wish, And doesn't care about me at all, because of this iam getting mental torture, and my health is going down due to panic attack And BP problems, I dont want to stay with him and spoil my life even more. Iam fear to stay with him Thats y my mom is staying with me too to take care of me when he is not supposed to do so, In that case also he is fighting with me because of my mom staying with me in bangalore, Thats why I came to my home town To avoid this mental torture from him. They are putting restrictions that I should stay in bangalore with him only, not to go anywhere and do job, even in another city soon I will get PR for canada and want to go there for job purpose as i have to look after my parents and want to live independently, My question is 1. Is my husband andd his father has the right to order me not to do job in another state ? 2.As we are newly married couple can i file a divorce against him? Up to how many months i have to wait? 3.As iam now staying in my patents home because of health issues and to avoid his mental torture and fight with him, If they file RCR against me? What can i do ?? please suggest me Thanks and regards
