If the person you're dating forgets your birthday, it can be quite disappointing and potentially a cause for concern, but it's also important to consider the context before drawing conclusions. Here are a few possibilities:
Different Values or Perspectives: Some people place a lot of emphasis on birthdays, while others don't. It's possible that he doesn't see birthdays as a big deal and didn't realize how important it was to you. In this case, it could be beneficial to discuss your expectations and feelings about special occasions.
Busy or Distracted: If he's generally busy or has a lot going on, it might have slipped his mind. While not ideal, it's possible and might not necessarily mean that he doesn't care about you.
Forgetfulness: Some people are naturally forgetful, especially when it comes to dates. If he's also forgetting other things, this might be the reason.
Lack of Attention or Interest: On the more concerning side, forgetting your birthday might be a sign that he's not paying enough attention to you or that he's not as invested in the relationship as you'd like him to be.
In any case, the best course of action is to have a conversation about it. Let him know that your birthday is important to you and express your feelings about him forgetting it. Depending on his response, you can then decide how to proceed with the relationship. It's crucial to communicate your expectations and listen to his perspective as well. Remember, everyone makes mistakes, and a good conversation might help you both understand each other better.
