What is he chooses his friends over me?

As an AI language model, I do not have access to specific details about your situation. However, I can provide some general information about why someone may choose their friends over a romantic partner.

There could be several reasons why someone might prioritize their friends over their partner. It could be that they have known their friends for a long time and feel a strong sense of loyalty and connection with them. They might also enjoy spending time with their friends and find that their interests align more closely with their friends than with their partner.

Another reason could be that the person feels a sense of independence and values their autonomy. They may not want to give up their friendships or make too many sacrifices for their partner's sake, as they want to maintain their own identity and sense of self.

It is important to communicate openly and honestly with your partner about how you feel and why their behavior is bothering you. It may also be helpful to evaluate whether your expectations and needs are being met in the relationship and if there are ways to find a compromise that works for both of you.
