Thank you for your advice. I'll be honest, there are some factors in our relationship that do make things a little difficult.
I also didn't realize this until I started this relationship, but I am deeply insecure. I'm afraid that I'm not good enough, that he'll get tired of me and leave me for another girl. I am not his first relationship, while he is mine. I am realizing that I do not trust him as much as I want to, but I think the only way I can develop this trust more is by communicating my needs with him. If I can't do that, I know that our relationship will be doomed to fail.
I am lonely, because I'm currently in my 1st year of college. I'm doing a lot with school, but I'm still trying to make friends. I recognize that in order to have a healthy balance, I need more in my life than just him. He definitely has more going on in his life than just me. That might be one reason for this jealously and nervousness about what he's doing. I also know that I can't expect him to tell me what he's doing all the time. If he expected that of me, I'd be out of there faster than you could blink.
He constantly does little things that prove that he likes me, and enjoys our relationship. We go to college in different cities, but only 20 minutes away without traffic. I don't have a car, so he constantly drives back and forth to see me. Sometimes, if we're both busy, he'll come up just for a little hello and a hug. He has a photo of me on his dashboard, he keeps all the art I make him, and I do believe that he's a good person who will listen to my needs.
He think's what he's doing is ok, because I don't say otherwise. You're right, he isn't a mind reader, and I can't expect that of him. I say to him that I value honesty and good communication, but I can't do the same myself.
I'm sorry for the rant, but I do appreciate yours and everyone's feedback. It's not only calming me down, but it's giving me the other perspective I needed.
Everything will be ok. This relationship is not wholly me but only a part of it. Instead of spiraling, I need to be proactive, and focus on what is there right now and not what could be.
