<human>: Can you summarize the given text in a few sentences?

So I've been seeing this girl for about 6 months now, and she's great and all that. However, she's got a tendency to get very bossy. Whenever she asks me to make plans with her (doesn't matter if it's concerning the next day or the next month) and my answer is yes, I better stick with it, lest she gets upset with me for changing my mind. 

I was raised with the idea of sticking to the plan if the person with whom you've made plans "suffers" should you cancel the plan. I do doubt my girlfriend suffered last night when I canceled lunch 5 days from now with her, yet she was really mad with me. It feels as if she's trying to control my decisions in our relationship with fear.

Furthermore, whenever I call her out on being angry for petty reasons, she gets way angrier, telling me that I'm "accusing her of being angry, which makes her angry".

During our 6 months together she has never been wrong ONCE and never apologized for anything, and I have a hard time believing I'm always the bad guy and she's always the victim. 

What should I do?
<bot>: My girlfriend doesn't allow me to change our plans and tries to control me with fear, and whenever I call her out on it she takes on a victim-role and makes me look like the bad guy.
