does he love me or does he not?

Well, Im dealing with some boy problems (like any other woman huh?) I have been involved with this guy for about 1 and 1/2 years and we are dealing with long distance. It is terrible. He lives in Kansas and I live in Colorado. We still talk just about everyday but there really is no substance to our conversations. Does that mean we really dont have anything to say, or are we afraid that we will just tell them something that really has nothing to do with them, and they wont care? Or is it because we're afraid that because they are here they will feel bad for not being involved in our life? For me I know when I talk to him and he tells me he is going out after work, I get a little worried that he will meet someone else, or that he might make a bad decision. But how do you tell someone that? I also get a little jealous because I wish I could be there to be a part of his life a little more, and just to spend time with him while hes out on the town. I really dont get to see him much at all because Im busy with school and work and he is really busy with work, and other financial issues. I guess I just needed to get some insight from some people who have been dealing with the same problem.
