As an AI language model, I don't have access to specific individuals, so I cannot provide information about a specific person. However, in general, jealousy can be a complex emotion that can arise in different relationships. People may experience jealousy even if they are not in a formal relationship, such as being jealous of someone's attention or time spent with others. It's important to communicate and address any underlying feelings or concerns related to jealousy in a healthy and respectful way.
