I can offer some general possibilities why your boyfriend might not enjoy drinking with you:
Personal Preferences: People have different tastes and preferences when it comes to social activities. Your boyfriend may not enjoy drinking as much as you do, and he might prefer other ways of spending time together.
Past Experiences: Negative experiences related to alcohol, either personally or from someone close to him, could lead to a dislike of drinking.
Health Reasons: Some individuals may avoid alcohol due to health concerns or medication interactions.
Personal Boundaries: Your boyfriend might have personal boundaries when it comes to drinking, and he may prefer to limit his alcohol consumption.
Communication Issues: If you haven't discussed this topic openly, it might be helpful to have a conversation with your boyfriend about why he doesn't like drinking with you. Communication is essential in any relationship to understand each other's perspectives and feelings.
Social Pressure: He might feel uncomfortable or pressured in social drinking situations, and this could be unrelated to you personally.
Past Misunderstandings: There could have been misunderstandings or conflicts related to drinking in the past, leading to his reluctance.
Different Values: Your boyfriend may have different values or beliefs related to alcohol consumption, and he might want to avoid it for personal or cultural reasons.
Remember, the best way to understand why your boyfriend feels a certain way is to talk openly and honestly with him about it. Respect his feelings and preferences, and if drinking is important to you, find other ways to connect and enjoy each other's company without alcohol being a central focus.
