Yes. Do you have a cell phone with texting? I know I said "don't go crazy" but it's fine to call or text sometimes. Even better, if you can get him on facebook or some other social media website, then you can just chat/message easily.
The point is, you want to get to know this guy better so you don't have to be interpreting "signals" that may or may not be there (such as "oh no! why didn't he come this week? maybe the weather?" -- you can just ask instead, or if you have a dialogue going, he'll probably offer the info freely).
That said, be careful to not get too emotionally involved before there is actually something there. You seem like an innocent guy; don't let your feelings get the best of you.
