Is a verbal lease for rental agreement upholdable in Texas?

My landlord wants me to move out after a few months so he can make more rent money. He kept promising to bring over a year lease, but never would. I have asked repeatedly for the written lease in front of others. I have a few witnesses, but only my teen son heard the length straight out of his mouth. My verbal lease is good till 05-10. Can he do this? Do I have any rights? - Is this your question? Add additional information
