Codependency isn't the term for "every bad relationship" There are certain symptoms that apply to people who are codependent and addicted to the situation they find themselves in. Op, in his other thread, has admitted that after reading about CD that it applies to him. If his personality wasn't so codependent, then he would certainly have left at least two years ago knowing that he's not getting his needs met. It's his own issues that keep him there. This hasn't anything to do with her. (although she has obvious sexual issues that need to be addressed and fixed but, which won't ever get done as long as he stays and enables her to be sexless and orgasmically selfish.).
