What is boyfriend introduced me to his son?

As an AI language model I don't know your current situation or your relationship, but generally speaking, if your boyfriend has introduced you to his son, it could mean that he sees a future with you and wants his son to get to know you better. This is a positive sign that your relationship is getting more serious. It is important to respect his relationship with his son and take things slowly, allowing the relationship to develop naturally over time. It is also important to communicate openly with your boyfriend about your feelings and concerns around this new development, and to be understanding and patient as you navigate this new dynamic in your relationship.
