Girls have been answering messages for a long time. How to reply?

The girl replied for a long time, maybe he didn't see it before, so you don't have to care too much about how to reply or how to reply.

Of course, if you want to get back at him, you can also not reply to his message for a long time and wait for a long time to reply, instead of expressing his dissatisfaction with not replying to your message for a long time.

If you really have doubts about his long-term failure to reply to your message, you can directly ask him the reason, and don't guess here, because guessing is the most likely to lead to misunderstanding. You can reply to her. Were you busy just now? I waited for you for a long time and didn't reply to my message. See what he says.
