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

I signed a year long lease that ends at the end of the month. I was unaware that I had to give 45 days notice (stated in lease) to my landlord that I would not be living here for another year. I only gave him 30 days and now he is saying that my lease automatically renewed for another year. I never had a new lease presented to me to sign and agree to with the new dates as well as my new rent because that is increasing 4%.

I am aware I did not read the lease thoroughly and give the proper notification. That is my fault, but can a year lease automatically renew without me signing it?
