The most obvious solution is: “It was fear that led me here”. That way his fear was not actively keeping him there. And it’s more relatable to Rey since she only just arrived, as well. Unless there’s something wrong with that wording?

Alternatively, we could hone in on his fear of Ben/Kylo, but I’m not sure how to word that while matching your other criteria.

If neither of those work for you, then I’ll just add this to the list for my other thread so we can focus back on the other important stuff.
