I work on a project for a client . the project supposed to be delivered in 3 months for a fixed price . It's a year since we have started the project and it is not finished yet . the responsibility for this delay is on both of us , They were asking for a lot of changes and i sometimes was delaying delivering some work .
but i am sick of this project and it grows with time and i don't really want to work on it anymore even if they doubled the price we are agreed on .
How to fire the client in this situation ? since i have a part of responsibility in delaying some aspects of the project.
note : i don't have a contract.
