Long distance relationship advice?

My boyfriend and I live 3 hours apart. I was just up there for the weekend, and am back home but having a hard time. I feel on edge and anxious..as if I'm not going to see him again. I know that I will, but why do I feel like this? Any advice?Long distance relationship advice?
I know exactly how you feel, only me and my boyfriend are 4 hours apart. This month will actually be our 1 year anniversary. All I can say is sometimes those kinds of feelings never really go away. They die down a little bit, but they're still there. It will get better. Sometimes I feel like it is so much worse though. It's almost like it comes in waves. The more you love and trust him the better it will be; at least that's what I believe. We can't see each other every weekend though, because of GAS prices, so we're limited to every other weekend, if we're lucky. We both work and are in college and he's in the ARMY, so we take what we can get pretty much. What I do is think about how much better it will be in the long run because we're both doing what we can now to better ourselves before we take that next step. We want to have our feet under before we make our big, BIG plans. But, I know it's hard, not going to get much easier, but everything will be okay. If I can make it this long, anyone can do it. Oh Yeah, not to mention, the distance has helped me realize that I don't have to be dependent on him to always be there, because, of course, he can't. I used to actually be a very dependent person. Anyways, good luck with everything. I can only hope that y'all are as happy as we are.Long distance relationship advice?
My cousin went through the same situation. He had this gf who lived about 7 hours away. It didn't work out, it was too far. But everytime hed come to see her he felt like he would never see her again.
