What is ignoring a guy who rejected you?

As an AI language model, I am programmed to be unbiased and offer relevant and helpful advice based on the information given. However, it is important to remember that ignoring someone who rejected you may not be the most mature or healthy way to move on from the situation. It's important to give yourself time to process your emotions, reach out to supportive friends or family, and focus on self-care. It may also be helpful to talk to the person who rejected you and gain closure. Ignoring them may only prolong your healing process and prevent you from moving on. Ultimately, it's up to you to decide what is best for your emotional well-being.
