My landlord doesn't allow me to wear mask indoor, what should I do?

My landlord couple doesn't allow me to wear mask indoor. The landlord wife says "If you wear mask indoor for the third time, get out. I will give you 3 days' time." ( I assume she was talking about notice period for eviction). I think she threatened me for eviction. But I still want to continue to wear mask to protect myself and others. She says I protect myself too much and I am selfish. She says "If someone else sees me wearing mask, they would think I have a problem and be scared of me. It would affect other tenants." In fact, the third day I was in the shared flat, the husband landlord said “We are very healthy. If you are so afraid, then you shouldn't live here. Masks don't actually protect you. You still would be infected if someone had it in the house”. I said "if you are infected, you wouldn't know even though you are healthy. Masks could minimize the chances of infection". I notice the landlord couple doesn't wear masks even when going out for gathering with friends. I am on a 6-month contract and all the rents and deposit are already paid. I think if the landlord evicts me for continuing to wear a mask indoors, I should be able to get back the deposit as well as my rent? I think the notice period should be 6 months during Covid? Currently, I wouldn't dare wear a mask indoor. But I think I should since it is a health concern and the eviction is for no good reason. The landlord wife says "If you want to continue to live here, it depends if you can change yourself. It is your problem." What should I do? Should I at least ask if the deposit will be returned to me and if there is a reasonable notice period for eviction?

In addition, I also accidentally broke a picture frame in the stairs of the house. Even though it didn't look expensive and I asked to pay for it, she said she purchased it from betting and money couldn't buy it back.

Start looking for somewhere else to live.
