What is when someone tries to make you jealous?

When someone tries to make you jealous, they are attempting to manipulate your emotions for their own benefit. This behavior can be immature and hurtful. The person may be doing it to gain power or control in the relationship, or they may be trying to test your loyalty. It's important to communicate openly about any insecurities or concerns in the relationship and to address any behaviors that are causing harm. If the behavior continues, it's important to re-evaluate the relationship and determine if it is healthy or if it's time to walk away.
