Weird Guy?

A guy I was chatting to asked me for my Snapchat so I gave it to him. He also asked for my number and I gave him that too because he genuinely seemed nice. After he added me, we chatted for about an hour but he started slowly getting weird. So, I blocked him and I blocked his Facebook in case he tried to reach out to me again. And he did.. he made a fake Facebook, messaged me and said “You blocked me on Snapchat.. Why?”. I once again, blocked this fake page and then he tried to call me! This is weird and I don’t know what to do 🤷🏻‍♀️
