Ask every girl or experienced person to send a short message to the girl you like, saying "Hello, I miss you", and then she will reply "Hi". Details.

Hello, I miss you ",and then she replied" Hello ".What did it mean? Didn't you see the last sentence? She just said hello. During your contact with her, didn't you feel any other feelings from her at all? If not, then I advise you to think clearly whether you want to continue or not, and whether there is any chance to continue. You can try to analyze what kind of personality he is, and then what kind of person he will like. If he doesn't feel, it's useless.
