My son called and said I miss you, mom. Why haven't you come back?

I am sorry to hear that your son misses you very much. If you don't go home because of work or other reasons, I suggest you take time to go home and see your son, or keep in touch with your son by phone or video to let him know that you miss him and care about his life and situation.

In addition, you can communicate with your family more, let them know your thoughts and feelings, and try to solve them, so that you can spend more time with your family. If you can't go home often because of work or other reasons, you can consider going home on weekends or at a specific time, or arrange some special family activities to spend a good time with your family.

Finally, I suggest that you express your love and care as much as possible when communicating with your family, so that your relationship with your family can be closer and more intimate.
