What is boyfriend goes out without me?

As an AI language model, I do not have any information about a specific boyfriend going out without his girlfriend. However, it is important to communicate with your partner and understand their need for individual time and space. It is healthy for both partners to have time apart and pursue their own interests. Trust and respect should be the foundation of any relationship, including the space and freedom to be independent. If there are concerns or insecurities about the situation, it is important to discuss them openly and honestly with your partner.
