This statement highlights the distinction between maintaining privacy in a relationship and keeping one's partner a secret. It suggests that while it's important to have boundaries and not share every aspect of your relationship with the public, it's equally important to acknowledge and be open about your partner's presence in your life.
The phrase "Keep your relationship private" underscores the idea that some aspects of a relationship should remain personal and not be subject to public scrutiny. This can include intimate moments, personal conversations, or specific details about the relationship that are meant to be kept between the individuals involved.
On the other hand, "Without keeping your partner a secret" emphasizes that while maintaining privacy, it's crucial to acknowledge your partner's existence and importance in your life. This implies that your partner should be recognized and included in your social circles, and you should not hide or deny their role in your life.
