How do you navigate this?

This question is for those who have used the internet (or apps) to make connections, whether it be friends or potential partners, with the full intention of meeting that person in real life eventually.

How do you get around the fear that things might not turn out well?

I have had people I have video called (or texted) and felt fairly comfortable with, but when we've met in real life, there's been no spark. Either there was nerves or lack of a natural bond in the first place.

Similarly, I've had the opposite - people I gelled with more in real life than when we would text etc.
