Hi, as in the title, I feel a little confused. Last Sunday I had a date with a girl. I had a great time, and she said she liked it too. Before everyone went their own way, we agreed that in the near future we would like to arrange another meeting. On Tuesday I called her and suggested, that we would hang out on Thursday. She replied that she would be happy to meet me, but the next day she would let me know if she was sure, because she had made a preliminary appointment with her friend. The next day I got a message from her on the Messenger. She wrote that this week she will not be able to make it, because she has a crisis at work. I didn't want to be insistent, so I just wrote back "ok". However, today is Monday and I didn't get any signal from her. This begs the question. Should I continue to wait for a message/telephone from her? Or should I call?

Thank you in advance for your help and answers.
