My boyfriend takes me home at night. I'll send him a message later and ask him if he has come back. He didn't answer the message, I called again, but he didn't answer! Why?

It shows that he pays little attention to these details! And he doesn't like you enough. He doesn't miss you all the time. He misses you less than you miss him! If a person really likes and loves you, he will care about your every move, information, telephone and other contact information. He will receive it at any time and reply as soon as possible! That means he doesn't love you enough! You can either communicate with him and tell him how much he cares about you and values you, or seriously consider the depth of contact with him!
