The term "red flag" can get confusing, especially when someone is young yet. What it means is a person who looks at others more as objects and they are the center where they need others to orbit around them to suit THEIR needs. They are the center, the god and their needs are the priority. It's never about YOUR needs, always about THEIR NEEDS being met.

When someone is young yet, that can feel familiar due to having to obey and fit into what a parent wants and how they run things. If someone picks a partner that is a naricissist, they continue to live their life around that person's needs and never get a chance to learn how to get their own needs met. This man is showing you this is EXACTLY what he is and how his needs are the priority and you are just the codependent.
