Long distant relationships.

How hard are long distance relationships? Me and my boyfriend have been together two years and his parents hate me. We've gone thing long and were fine but that's because we went to the same school. Now they want to move him to Hermitage Pa school or to Barkeyville. We don't know where he's going. If he goes to Hermitage, we'll see each other at school. But if he goes to Barkeyville, I get to probably move in with him and his grandfather. This summer though, we have no way of talking at all because he will be at his grandpas and his grandpa doesn't know he has a phone and he'll be at work all the time with his grandpa so he won't ever have time to talk to me. What do I do?
Sorry for the length.
