2. Be Honest: Speak out about how his actions have affected you and made you feel. Being honest about your emotions can make him feel guilty for what he’s done.

3. Ignoring Him: Temporarily cut off communication with him. This may make him feel guilty as he senses that his actions have caused a strain in your relationship.

4. Emotional Distance: Create some emotional distance between the two of you by being more reserved in your interactions. Pulling back can make the Libra man analyze his behavior and see how it is causing pain.

5. Remind Him of Past Mistakes: Casually remind the Libra man of past instances where he has made similar mistakes, illustrating a pattern that he should feel guilty about repeating.

6. Turn to Friends: Share your feelings with mutual friends and let their opinions impact his sense of guilt. He may reconsider his actions when he realizes that people close to him are aware of his wrongdoing.

7. Take Care of Yourself: Focusing on self-improvement and well-being will show the Libra man that you are independent and don’t need him to be happy. This can trigger feelings of guilt for failing to provide support or contributing positively to your life.

8. Showcase His Lack of Empathy: Point out instances where he has failed to understand or empathize with your emotions, making him feel guilty for not taking your feelings into consideration.
