Mentally tierd and troubled by in laws

How can one get divorce if the mother in law says that she wants a boy child and husband is asking for child and do not give me name money , ex he gives 2000 rs at the end of the month . He takes me to Bhutan and makes me climb a mountain in my menstrual cycle even after telling him that I’am feeling fatigue. I’am at my parents home since 2 months and I just can’t go back have sex with him and enjoy . I’am very unhappy with this naval officer whose parents only want dowry . When they had come to see me my parents asked are there any demands , give the list but rather than that my mother in law came inside the bedroom and said we want 80 grams of chain . They are Tamil and I’am a north India born and brought up in Mumbai and our mentalities don’t match. My husband doesn’t support me for working in airports . He directly told it’s a fraud job . He didn’t even ask once that if u can trust them then u go and find it and start working. He seeks help from outsiders but not from wife & family
