You need to ask yourself one question - do you love them? If the answer is yes it wouldn't matter if you lived 10 hours apart. Everything is worth it for love. If you're not sure you love them, go out on some dates and compare them to your guy. You will soon see how special (or not) he is and whether he is worth the effort.
If you both feel it's worth it, then it is. It will be a bit harder than a "normal" relationship, but if you want to be together, you can make it work.
If it's really worth it then move closer to each other. If you're completely serious about it then get married and move into the same house. Otherwise... no.
Well speaking from experience, If the other person is mutually serious about their feelings for you and willing to put forth an earnest effort to make the relationship grow into more than just being friends or hanging buddies, then I would say yes. True love will not be hurt by time spent apart or distance. However, keep in mind that in order to get to trully know someone you have to spend time talking with them and being in their company. Get to know all you can about this person by asking as many questions as you can and listening to what they do say as well as to what they dont say. Good Luck your going to need it.. answer If you both love each other then yes. Do you dread going over there? If you do then you only like that person. If no then you love her & it dont matter how far away you live from each other.
