I texted that girl for several days, but she only replied one, saying that we don't know yet. Take your time. What if I sent a text message and she still doesn't reply?

The point is: Do you really like her?

1) that is: then continue to send text messages, say some things or jokes that everyone is interested in, and gradually integrate into her life.

Be careful not to be too frequent, it will be annoying and give people a feeling of being a mother-in-law It is best to say interesting things once a day or once every two days. Talk to you later. (Half a month at the latest, you can reply. Don't send it unless you reply. If you ignore it in a couple of days, there will be no chance. If you ignore it ...)

2) No: Then be tough. Say I ignore you, just don't like her. Keep posting. If I ignore you, it is a waste of time.
