This was a tricky relationship problem that needed to be handled according to the actual situation. If the ambiguous information between the boyfriend and the female student was only necessary for work, then this behavior might not be ethical or violate the school's rules. If this behavior causes you harm, you can consider taking the following measures: 1. Talk to your boyfriend honestly and let him know your feelings and concerns. Ask him about his thoughts and try to find out the reason behind his actions. If this was a simple mistake, he might have realized it and corrected it. 2. Evidence: Collect evidence and retain all relevant documents and information. If your boyfriend continues to send ambiguous messages, it may cause him more trouble and help you prove that his behavior is inappropriate. Leave: If your boyfriend is unwilling to change his behavior or the communication between you does not produce positive results, then you can consider leaving him to find someone more suitable for you. No matter what you do, make sure that your decision is based on your true feelings and rational analysis. Also, remember to seek support and help from friends, family, or professional advisors.
