Forcing the first wife to live with the second one in the same apartment

I have been separated from my husband since July 2019. I live separately with our 10-year-old daughter. He lives in the same building with his so-called second wife and her two boys from her previous marriage.

I am Christian and he was a Hindu when we married in India but he claims to have converted to Islam and remarried. I am a housewife and totally dependent on him.

I would also like to sue him for maintenance as he doesn't give me much. My immediate concern is that he is forcing me and my daughter to move in to a 2 bedroom and live with them.

I am most definitely against this. He said that the contract to my apartment will finish on 25 July. What can I do to avoid getting kicked out by him?

I have only 6 days. Can someone advise me of the quickest action?
