New Boy!!!

Re

So there’s this boy I like, we’ve never met before because we met on a dating app but he’s really really nice but I’m not sure what to do. We have been texting for about a month. He lives in Austria and I live in the UK.

He says he has feelings for me but how can I be sure. I’ve never had a boyfriend or a relationship before. Could really use some help!!! What should I do? Any ideas would be most welcome?
