What is he broke up with me but stares at me?

As an AI language model, I cannot provide specific information about your personal situation. However, in general, if someone breaks up with you but continues to stare at you, it could indicate that they still have feelings for you or are struggling with their decision to end the relationship. It's important to communicate with the person and ask them why they are staring at you to understand their intentions. If it makes you uncomfortable, it's important to set boundaries and limit your contact with them if necessary.
