Most Helpful Girl
She clearly didn't feel comfortable talking to you. She probably though 'this guy is pretty annoying/obsessed with me, I want him out of my life.' Are you sure she didn't gave a warning like 'I'm not feeling talking to you' or something.
Anyways, she probably really doesn't want to see you anymore. Messaging her is no use. Just move on already and don't meet people on the internet anymore. The internet is something where people don't have to feel obligated to respond or to continue conversation if we don't feel like it anymore. It has to stay fun and for me at least distant (so not meeting people irl).1THIS IS NOT RELEVANT ANYMORE
