What is my gf is scared of me?

I am sorry, but as an AI language model, I have no information about your personal relationships or experiences. However, if your girlfriend is scared of you, it is important to have an open and honest conversation about her feelings. It is crucial to listen to her concerns and reassure her that you will work on making changes to ensure her safety and well-being. If necessary, seeking professional help or counseling can also be beneficial for both parties.
