In the morning, she asked me good morning and wrote a long paragraph. I woke up late and it took me almost an hour to reply, so she ignored me all the time. What should we do?

In the morning, she asked you good morning and wrote a long paragraph. You didn't reply in time, so she ignored you. It seems that your girlfriend likes you very much and depends on you, but she is a little sensitive and willful. Maybe she cares too much about you. She thought you saw the message and deliberately didn't answer it, so she didn't care about her at all. You can apologize to her and tell her why you didn't reply to her in time. She will be angry because she loves you. If she comes to her senses, she will be fine. You behave better, wait patiently and sincerely for her to repair her mood, and she will talk to you when she is in a good mood.
