Feeling have absolutely NOTHING to do with a contract and if you have been renting the place, even paid for one month, then you HAVE a contract. You owe last month's rent and you must give proper notice. If you don't give notice, then you will be evicted so that the landlord can legally re-rent the place that you are renting and you will also owe at least for the month following your move out month, probably more. Playing stupid games when landlord & tenant law is so black & white is just plain stupid. You will regret it in the end.
