Its tough, because if you act too "clingy", the relationship will lose it's challenge. I for one don't like easy relationships. lol. I enjoy a good argument here and there. It helps spice things up sometimes.
The perfect test is to just chill out and let it flow, hold off on him a bit and see if he comes to you.
Really, you guys have to talk about what you guys want in the relationship. You also have to understand that he has priorities. I mean, I'm not saying that it's good that he has you last on his "to-do" list, but college comes first.
Also its not really healthy to see the person everyday in the beginning of the relationship. You have to have time to miss each other. He's used to having alot of his own time and being free since he's never been in a serious relationship.
All in all, if he loves you like he says all you can really do is trust him. Its up to you whether you can take it. You're better off talking to him about it and being straight up. Then you can figure out if the relationship is really worth it or not. . .
