What is when she tries to make you jealous?

As an AI language model, I do not have any personal experience to give information about when someone tries to make someone else jealous. However, I can provide general information about this behavior. When someone tries to make you jealous, they might intentionally flirt with or show interest in someone else in front of you, talk about their past romantic experiences or their current crush, or try to make you feel like you are not important to them. This behavior can stem from insecurity, a desire for attention, or a need for control in the relationship. It is important to communicate with the person and express how their attempts to make you jealous make you feel.
