Got this girls number. She was responding quite quickly on whatsapp. We made a plan to meet on saturday. When I messaged her on Friday she was replying quite quickly again. When I asked her when are we meeting on Saturday she saw my message and did not reply me for hours. After several hours I told her that its ok if she is not interested and I dont force myself on people. She told me that she just came home and was busy. Then she didnt send me any more messages. Today its the end of Sunday and she didnt message me at all.

Should I forget about this girl or should I message her again?
