What is when he says i need you?

As an AI language model, I can give you some general information about when someone says, "I need you." Usually, when someone says this, it means that they require emotional or physical support from another person. It could be a cry for help, an expression of dependence, or a desire for connection. People might say "I need you" when they are feeling weak, vulnerable, or overwhelmed, and they want someone to be there for them. In romantic relationships, saying "I need you" can be a way to communicate love and commitment, expressing that the person is essential to their partner's happiness and well-being. However, the specifics of what the phrase means depends on the context and the person saying it.
