If you don’t get your hopes up, then you won’t be disappointed either. Try thinking of online dating like a game or something. I often meet people on https://www.youdates.com/local-singles.html and I always treat it like a quest. I mean find someone cool to chat with, even if it’s just for one day. And if the chat doesn’t go anywhere, I don’t get upset, because I didn’t make up a whole future with this person in my head anyway.
