Am I not being patient?

I started seeing this guy about a month and a half ago. We went out a bunch of times and talked constantly. However, the last 2 weeks have been close to complete radio silence. I texted him a week ago and bluntly told him that I want to see him. I figured that if he'd lost interest, he'd give me some excuse or not reply. But instead he offered to pick me up after work and drive me home, because that's all the time he had since he had an assignment due first thing the next morning. He told me about how stressed he was over school work which is expected since he's a chemical engineering student. Only thing is he mentioned that he was going away that weekend for a bachelor party. I expected that he would at least text me a bit that weekend, since he obviously wasn't studying, but in reality I haven't heard from him since he dropped me off. In fairness, i haven't contacted him either and he did tell me that he would be much more free in a couple weeks. I'm just worrying about it because I was so interested in him. Am I expecting too much from him so early in the game? Is he stringing me along? Am I overreacting? Thanks for your advice
