My boyfriend and mother were sick before. How can I send a message to show my sincerity? I really care about him.

Stop thinking about him. Women often have unfinished feelings under the banner of caring. I hope that when he is most vulnerable, I can get his concern, make him grateful and miss you. If a woman is deeply hurt by a man, she won't do it at all, and she will want to scold his family to death. If you think you can still play, you can send a message. If it's impossible for you, I advise you to keep your last dignity. If he has no interest in you, he won't care about your concern. If people don't reply to text messages, it's a shame, isn't it?
