Send a message to a girl saying that she misses her, but she doesn't return the message ~ What is the reason?

I'm glad to answer this question for you. My personal views and suggestions on you are as follows. First of all, you described sending a message to a girl saying that she missed him and she didn't return. You don't know why or why. First of all, there are two situations. The first one is that this girl didn't see your message, so she didn't reply to your message. This is more correct. What is the second situation? In other words, this girl didn't feel puzzled when she saw this message you sent, and she didn't know how to reply, so she didn't reply to your message. There is also the most common situation, that is to say, in addition to these two situations, the third situation is this girl. She doesn't like you at all, so she doesn't feel the need to reply to this message. Generally speaking, these are the three situations.
