If it doesn't work out, it's fine. Soooo many first dates don't work out. It's painful to date and it's normal.
I would have the attitude that you are just going to meet this person and it's not a huge deal if it doesn't work out. Don't put pressure on yourself that this is going to be some magical moment. It's just a person on the other side, with lots of flaws and insecurities and may even not be a nice person.
Try to chill and see if you are a good fit together. If not, it's fine.
It's all about if you are a good fit together. Maybe you go there and she is annoying and awful. It's possible. So just relax.
