How does dating even work for introverts?

I'm so serious right now. Like, obviously I know how it should work in theory, but how do you trust someone enough to get closer to them? I go on dates and it's all good, but most of the time they're moving way too fast for me! I feel like I first need a good friendship as a base for anything more, because I will not trust you, no matter how kind you are. How is everyone else so fine with it?

I can't seem to move on from my first relationship because that one was organic. We started off as friends and we were both interested in each other early on, but worked on our friendship before ever making a move. We weren't even officially together but man I saw a future with this girl. So you'd think I can just start with friendships but that doesn't seem to work out either. Last week I met up with this girl and I thought we were meeting as friends, just for her to later clarify that she thought this was a date.. it's so tiring.

As an introvert, I need time to open up and feel comfortable. I'm not going to feel connected enough to you after meeting you once or twice. The whole "spark on the first date" thing feels impossible for me. Is there something wrong with me? How do other introverts navigate this?
