Long-Distance

So my boyfriend and I have been together for a year (well, it'll be a year next month) and a majority of our relationship has been spent long-distance. We started dating at the end of his senior year/my junior year and now he's at college 4 hours away. I don't regret my decision, I don't plan on breaking up with him, and we both say we want to keep doing the LDR thing as long as we have to. But no matter how much I want to stay with it, it still HURTS like HELL. I guess I'm just wondering if there are any other girls out there in LDRs and if you have any advice on easing the pain.
