My question involves an eviction in the state of: NY

I rented a house with a lease that has no termination date, we agreed that we will be using the house until we relocated to Florida on or about the months of July or August 09. I have not been able to get the job in Florida yet, and my landlord bc of personal problems is requesting me to move out. Can the landlord kick me out of the house? (family with one child, No pets, No late payments on the rent and no damage to the house) We have no place to stay and landlord says that doesn't care because needs to move back bc of personal problems. Please advise me on my rights. Thank you.
