Should I give up on him?

I have been talking to this guy for a while and we talk every day. I have noticed he has been a little distant but I understand as he actually has been busy with work and school. He texted me good morning this morning (like he does every morning) and asked how I am doing, I responded but he hasn’t texted me back and it’s been over 2 hours. I went on Instagram and noticed he posted a story a few minutes ago about a football game that’s on. Should I be worried?
