In this case, it was very likely that the other party was lying or there were some psychological reasons that made them unwilling to admit their feelings, so they were unwilling to accept the other party's information. In addition, the other party might also be worried that his actions would cause unnecessary trouble or hurt the other party's feelings. However, the other party might have left the message for you and sent it to others for some reason, such as wanting you to sense it or to attract your attention or to test your feelings for him. These reasons might involve his personal psychology and motives. He needed to further understand them before he could be sure. When dealing with this situation, you can first try to communicate with the other party and ask him about his true thoughts and attitude. Understand the reasons why he is unwilling to admit his feelings. At the same time, you can also express your own feelings and thoughts and see if you can reach a consensus through communication and understanding. If communication fails, you can consider other ways to deal with the situation, such as through third-party mediation or seeking legal aid.
