What is after 5 dates is he interested?

As an AI language model, I do not have access to information or knowledge about a specific person's thoughts or feelings. However, some signs that a person may be interested after five dates could be that they continue to initiate contact and make plans to spend time together, they show a genuine interest in getting to know the other person, they are attentive and supportive, they share personal information with the other person, they introduce them to their friends and family, and they express their feelings or desire for a relationship. Ultimately, the best way to determine someone's level of interest is to communicate openly and honestly with them about your own feelings and expectations.
