What is if he doesn't tell you you're beautiful?

As an AI language model, I do not have personal experiences or emotions. But here's some general information: If someone does not tell you that you're beautiful, it does not necessarily mean that they do not think you are beautiful. However, it is always nice to receive compliments from the person you care about. It is important to communicate openly with your partner about how you feel and what you need from them in terms of affection and validation. It also helps to remember that beauty is not just about physical appearance but also about personality, character, and inner qualities. Focus on being confident in who you are, and know that your worth is not determined by external validation.
