When he texts you after midnight, it means that you didn’t pop into his head until the end of the day. It means that he didn’t have the idea to text you until the sky grew dark and he realized how empty his bedroom felt without anybody there.
When he texts you after midnight, it means that he doesn’t care about your plans. He doesn’t care about inconveniencing you. He doesn’t care about how rude it is to invite you over at the last second when you’re already in your pajamas, ready to fall asleep. He doesn’t care about how you probably have to get up early for work the next day or how the last thing you want to do is shower and put your makeup back on and drive to see him on such short notice.
When he texts you after midnight, it proves that he only wants you for one thing. He doesn’t want you in the daytime when you can go out for a nice dinner and have an actual conversation. He wants you in the middle of the night when you only have time to grab a drink and jump in his bed. He wants you when you’re going to be out of his apartment as quickly as you got there.
When he texts you after midnight, it isn’t a compliment. It isn’t something you should be flattered by and brag to all of your friends about. It’s something that should raise a red flag. It should warn you about his intentions. It should give you a hint that he isn’t talking to you for the right reasons, for the reasons that you are secretly hoping.
When he texts you after midnight but leaves your messages unanswered the rest of the time, you shouldn’t take it as a mixed signal. Take it for what it is. Proof that he only wants you when he’s drunk and alone. That he isn’t willing to put effort into planning a date. All he’s willing to do is send out a text and hope that you come running to him when he calls.
When he texts you after midnight, you should ignore his messages. You should see if he will answer you after the sun rises. See if he still wants to hang out with you during a reasonable hour. See if he actually has feelings for you or if he just wanted your skin pressed up against his for the night.
When he texts you after midnight, go to sleep. There is no point in meeting up with him. There is no point in messaging him back. Ignore him, because if he liked you enough, he would send you good morning texts. He would send you good afternoon texts. He wouldn’t wait until the middle of the night to talk to you.
If he only texts you after midnight, don’t bother with him. If he only texts you after midnight, he isn’t worth the time it takes to read his message.
