Can the wife ask for maintenance in case of separation without divorce?

I am a non-Muslim and got married in the UAE 2 years back. I have a residence visa under my husband's sponsorship.

My husband and his family have kicked me out of the house been almost 2 months and I do not have access to my things which are at my in-laws' house.

Once he made me leave the house, he answered my calls for the first few days but has completely stopped answering my calls, texts.

And if I ask him to meet or let me come home he does not allow that anymore and says his parents do not want me to come home or to continue with the marriage.

I am currently unemployed and, do not have a place to stay.

What are my rights as a wife and how can I file for financial support and maintenance without divorce?

And, do I need a lawyer to file this case against him?

Thank you,

H
