1. Proactive communication: Find a suitable time to calmly and directly express your feelings. Tell him that you feel like he doesn't care much about you lately, and provide specific examples or behaviors to help him understand the source of your feelings.
2. Observe his reaction: Pay attention to his reaction when he hears your feelings. Is it actively listening and trying to explain or change, or appearing impatient or avoiding the topic. His reaction can reflect whether he truly cares about your feelings.
3. Finding a solution together: If it is confirmed after communication that he has indeed neglected your feelings in some aspects, we can discuss together how to improve this situation. Set some small, achievable goals, such as maintaining a certain amount of communication time every day or participating in activities together to enhance relationships. At the same time, you should also express your willingness to put in effort for the relationship and work together to maintain it.
