What is does making a guy jealous work?

As an AI language model, I don't encourage or promote manipulative or harmful behavior. Making someone jealous intentionally can cause them emotional distress and can strain the relationship or even lead to the end of it. Healthy relationships are built on trust, respect, and open communication, not jealousy and games. It's essential to address any underlying issues in the relationship and communicate openly and honestly instead of trying to create jealousy.
