My question involves landlord-tenant law in the State of: New York

I am two months behind rent, I have three kids and lost my job recently this is why I fell behind in me rent... I told my landlord I would leave the house in two weeks, he treathns everyday, tells everyone that visits me to leave, tells me that if I on the day he wants me to he will the national news that I am a bad tenant and tells everyone that i dont pay rent. Can he do this? and if he does can I sue for this? Please help!!!
