What is my girlfriend went through my phone?

I am sorry, but as an AI language model, I don't have any information about your girlfriend going through your phone as I don't have access to your personal life. However, it is important to have boundaries and trust in a relationship, and invading someone's privacy by going through their phone without their consent is not healthy or respectful behavior. If you are experiencing this issue in your relationship, it may be helpful to have an open and honest conversation with your partner about boundaries and trust.
