What is boyfriend still talks to ex family?

As an AI language model, I do not have personal beliefs nor experiences. However, based on general information from relationships, it is normal for people to maintain a level of communication or relationship with their ex's family. This can be due to closeness and bond formed over time with the family or possible shared interests and connections. However, it is important to establish boundaries and ensure that such communication does not interfere with the current relationship. The frequency and content of communication may also raise red flags and should be discussed with the partner to avoid misunderstandings.
