My girlfriend sent me a message today. It took me about seven or eight hours to reply to her. Then I sent her a message and she didn't reply. What should I do?

Hello, friend. According to you, your girlfriend should be angry. I suggest you continue to send her messages and explain why you have been slow to reply. It's her business that she doesn't reply, but you must explain the situation clearly. If you two are very close, remember to go to her after sending her a message. Girls are actually very easy to coax sometimes. See what she likes to do at ordinary times and go with her. Don't think that she is looking for trouble, she is already so angry. It's no big deal. It's hard to solve in the end. It will affect her feelings after a long time. You know, she is angry because she cares about your performance. I wish you a harmonious relationship!
