My one year lease ended in 2017 is my cosigner still liable

...I had know other choice.

Sure you did - you could have moved. Having "no choice" is different than having a "difficult choice".

The increase was for heating costs that in the lease are covered by the landlord. I did pay it because I had know other choice. He told me that it would only be for winter then after winter I gave him the 1795 and he said know I need to give him the 1895. I told him what he told me and he said know we need to see how it is for the year. Totally changed what he said.

For future reference, do things in writing.

Don't depend on verbal agreements. The other party can claim later they meant something else, or that you misheard them.
