long distance

Help!! I've known this guy fo about two years and we have always been really good friends and hit it off amazing. Recently we started to take it a little more seriously and he wants to try long distance (and by long distance I mean three hours which I know isn't that long) I know it's not that far but he only gets weekends off and I work most weekends so seeing eachother is really hard. I'm so on the fence and don't know what to do. My heart is telling me to do it because I'll kick myself if I never find out how we could be together but I'm worried about the distance and how it would work. Anyone got any advise?
