Father In law harassing me

I got married in Oct 2019. I am a govt employee and my husband is a mariner so he stays onboard ship for about 6/7 months. After 1 month of our marriage he joinedhis duty. So I was supposed to stay with my father in law ( my sis in law lives in Australia and my mother in law died before we got married). Few days things were good. By one day my father in law asked me to sleep with him and at times touched me inappropriately. This continued for about 4/5 times even after telling him that this is wrong. I recorded it sent it to my husband. He told his sister and somehow they tried to manage it and asked me not to file a complaint. By my father in law on other side files a complaint in local police station that few men visit his house during night and I am having wrong relationship with such men which is just a lie. He keeps me lock during night. He kept on tarnishing my character . There was no further action taken so leave the thing here and I don't tell my parents about this . Now again my husband left for his job and now he again started doubting keeping me inside , lock me during night hours and at times blames me that I steal his money and having duplicate keys to rooms and his locker. I sometimes think he is having some mental disorder but he's good his daughter her in-laws, outside. I am 5 months pregnant and I am a govt employee I am unable to bear this mental harassment. He don't even listen to my husband. I sometimes feel that I should file a complaint against this mental harassment. I am happy with my husband only because of his sakei m keeping quiet. Bt he scares me of lodging a false complaint against me of theft and harassment. We both are planning to move out from here and buy a new place but still it's almost 3+ months still left for him to come home. I am govt teacher I don't want to loose my job because of this psycho and on the other hand don't want to take the issue outside my home
