Should I still try to talk to him?

These past couple weeks of being back at school, I began talking to a guy that I really enjoyed hanging out with. The first week we were talking figuring out when we were going to hang out was difficult because even though are dorm buildings are right next to each other, I am an athlete and he is an RA as well as having another job and both of us have a heavy course load this semester. When we were finally able to hang out last weekend, I was under the impression that we both had a good time and he kept on making comments about future plans and us going out again. However, this past week the only time we have spoken is if I have sent him a text first or we say hi if we pass by each other on campus. Because I have not sent him a text in a couple days, we have not spoken. From the couple of times we did speak earlier in the week, He has told me that he’s been extremely busy as well as exhausted. Should I still try and text hi or should I let it go? Should I ask him about what is going on? I hate being the first one to text multiple times in a row because I get nervous that I am being annoying, and I don’t want to seem psycho/clingy for asking why he hasn’t been talking to me.
