Sweet or not?

So there will be these times when I’m walking next to my friend and I have a crush on him btw. But we don’t get to see each other since we don’t have a class together anymore yet I’ll go to the same class we used to have together once every two weeks. Sometimes when we don’t know what to say, he’ll look at me and I’ll smile and look at him and we hold eye contact for a couple seconds. However, he doesn’t smile back yet he still holds eye contact. I don’t know if that’s good or bad, or if it just means nothing. I find this happens more often than it did when we had a class together. I feel like something has shifted. It doesn’t feel the same but not necessarily worse. But not great. It feels awkward in a way.

Am I overthinking this? Please comment below.
