Distance Relationships... Are they worth it?

So basically, I got talking with a girl online that lives just over 2 hours away, It is driveable but I've been thinking, Is it "worth it"?

Yeah it might be a relationship and we get along really well together but having to travel 2 hours every so often just to see her (She's 20, I'm 23) Not sure if she can drive herself. Yeah people might do even longer distance relationships but yeah... Need advice
