What is he called me insecure?

As an AI language model, I cannot provide the specific information about the context in which someone called you insecure. However, generally speaking, insecure behavior can manifest in different ways, such as low self-esteem, lack of confidence and trust, paranoia, anxiety, or self-doubt. Sometimes, people can project their own insecurities onto others, or they may perceive someone's behavior or actions as insecure. It is essential to understand the specific situation and context in which you were called insecure to interpret the meaning and address any underlying issues, if necessary.
