Boyfriends always send text messages in the middle of the night and don't return them.

The reason why a man doesn't reply to your message at night may be that he is really resting, or that he is not interested in you, so he doesn't want to reply to your message, or that he saw this message but didn't know how to reply to you. Men don't return messages, or some men are naturally indifferent, which makes you feel that you can't fathom him.
