So the situation is, there was a girl in my class that changed the class after about a month. We had some basic small talk but nothing special. A week or so after she left she added me on snapchat, and started chatting. A few days ago she called me out of the blue on told me she will take some weeks off to travel to China for vacation. I started to write her per WhatsApp but she starts to leave me on not seen, all though she is online. Is this a test? She answeres but very delayed and still snaps. I wanted to ask her if she wants to take a drink with me after she comes back to initiate so I won't become a orbiter.

What do you guys think?
