How do you know if they’re “the one”?

I’m 24 and I can’t seem to get how people know.

There’s this one guy I like. He’s extremely funny and always makes me laugh, often just to make me smile. He’s very quick to say sorry and try fix things. He told me he had a dream a few days ago where he had a son, woke up and felt really sad- he really wants to be a dad.
He’s never pressured me to do anything and he’s still a virgin at 21, so maybe it’s just the nerves with that one?
We used to like each other and I ended it because he never made moves on me or put much effort in so I felt he didn’t actually want me. This time round he stopped smoking so he’s more alive- he just made me rings made from spoons today…
He doesn’t have money or much ambition when it comes to jobs or working.
He genuinely does have a good heart and is a great person.
I’m at a loss what to do
Making choices are so scary.
Also, don’t come for me, I’ve been alone since I was 16 so
