How can I deal with a long distance relationship

I would recommend talking to each other a lot. You obviously love him, and he loves you too I assume, and since you can't be together physically be together on the phone and in your mind. Whenever you are doing something in Oregon that you used to do with him or wish you were doing with him, imagine you are. Keep him close to your heart by keeping him in your mind all of the time. Also, make sure he knows how you feel about him. Even though you might think he knows, it's always nice to hear it from the person you love. The last thing I can think of is keeping things of his or that remind you of him in your room. Make your computer background his picture or put pictures of him up on your wall. This might sound kind of cheesy, but I think it will help. On a final note you ought to know how lucky you are that you and this guy are close enough to have a long-distance relationship. They often end up with one person cheating on the other and then the two who were in love at first go, their seperate ways. I can tell that you love him and that it would break your heart if he did that to you, so ask him a few probing questions to make sure that he doesn't cheat on you. The exact thing that I am hoping you will prevent is exactly what happened to me. My girlfriend cheated on me with a guy when she was in New York for a few months and I still haven't recovered from it six months later. Good luck.

Sorry to be a negative nancy but long distance relationships have a low success rate and an even lower one at your age (from experience and statistics).
You can try anything from phone sex to web cams. Web cam is especially useful as you can both see each other.
