Are long distance relationships worth it?

Natasha
I live in the Bronx and the guy I like lives in NJ . That's only 3 hours away, but even planning on going over there like at times by MYSELF kind of scares me😕. He said he has tried long distance before and it never worked, but I want him to give me a try. So my question is, is it worth it, and how can I make it work?
