Can I sue a landlord who has vacated me from his tenement after knowing I was a lesbian?

I'm a butch lesbian, at the time that I rented the apartment the landlord kept referring to me in the male pronown. I didn't correct him because he was an older gentlemen and did not want to start my living situation awkwardly. After 2 weeks, he then realized I was female and the other female in the apartment was my partner. He then refused to give me a lease which he said he would do 30 days after moving in, has incessantly harrassed my partner and I about a plethora of ridiculous things like not opening windows, having no plants by window sill. He walks outside my window and peaks in. Has opened my door on more than one ocassion without permission and have been verbally absuive. I want to know if I have a possible discrimination case. Thank you.
