I'm not going to compromise
What aren't you going to compromise on?
I know what I want, I don't want to be in this relationship any more.
If you no longer want to be in the relationship than it is fine that you do not want to compromise. Go ahead and end things and you will be free to spend your time however you wish.
If there is no chance of success then I don't want to continue.
I'm glad you realize what you need to do then. I hope she doesn't take the breakup too badly.
