Relationship Advice?

I started dating my BF 9 months ago. About 2 months ago I left the state we both lived in to go do a 10 month residential volunteer program. We decided we wanted to stay together (breaking up wasn't even an option in his opinion). Since being in the program I realized that while he truely is a WONDERFUL person, our lives are going in completely different directions. We both want different things out of our lives. He doesn't know that I feel this way. On top of it he says that I'm the only thing that keeps him going and the only thing that makes him happy. He doesn't have many friends at all and works a job he hates. I am his first serious girlfriend. He's been depressed lately. To top it all off I met a person whose company I really enjoy and whom I can see me working out with. What should I do? I don't hate or dislike my boyfriend. I think he's a wonderful person. I feel horrible. I';m going home for x-mas and he paid for my ticket and his family is buying me a present.Relationship Advice?
You have to do the only thing you can do. You've got to be honest with him, and you should do it in person. I'm in the military, and fully understand the effects of being away from the one I love for long periods of time. There was a point in her life where she felt she couldn't handle the distance... she was honest with me though. She went out on her own to figure things out, and got hurt in the process. Due to her being honest with me, I was able to forgive her, and understand she had to do what she had to do, to figure it out in her own mind. Now, I trust her more than ever.
