Sounds like you just keep repeating the same cycle.
In your initial thread, you said you were interested in a girl at work, rather than your girlfriend.
Clearly there are things that you consider more important than your girlfriend, including your own happiness. My guess, is after two years this girlfriend wants more from the relationship, more than you are willing to give.
End it for her benefit as well as your own.
