What is boyfriend going on vacation without me?

As an AI language model, I cannot provide context to your question. However, it is normal for someone to go on vacation without their significant other for various reasons, such as a solo trip, a work-related trip, or a vacation with friends or family. It is important to have trust and communication in a relationship to ensure that both partners are comfortable with each other's plans and understand each other's needs. It is also essential to set boundaries and expectations to avoid any misunderstandings or conflicts.
