Why would someone block me without any reason?

I met this girl here I followed her then she followed me back. First day passed, then the next day she texted me "I will only go out with the guys I have chemistry with" So Convo started there. She seems to be into me and wanted to hangout e. t. c is just Iam so far, so that is impossible at the moment. But I told her when I gonna travel to that place, and she said "I can't wait". Iam travelling there for my studies. It was in the plans even before I talk to her. We flirted a lot and xo xo but when I went deeper asking her some normal questions want to know her a bit, she just remain quite ☠️ then I asked her "why so quiet thou? Being busy?" I didn't send her any text again. 2 days passed I just found out She blocked me 😂 So I just remained asking myself what's wrong really? 🤔 I know I haven't said or done anything stupid but this has just happened.


So I wonder what did I do wrong? Any idea you have? you ever got something like that here? Or even somewhere?
