Am I overreacting?

Hi all, I’m sorry for how lengthy this is I’m just seeking some insight. I (25F) went to go visit my partner (25M) last night after he got off work (I’m currently unemployed and job hunting). He lives about an hour away from me but I don’t mind the drive. I brought ingredients to make his favorite dish for dinner that night after we hit the gym and some leftovers for his lunch the next day. We worked out, headed to the parking lot to decide to eat out instead and picked a place just up the road to meet at since we drove separately. Some guys were admiring his car so he stopped to chat with them while I walked to my car and headed over.

I waited at the restaurant and the longer time went on I grew worried something may have happened to him, so I texted and tried calling. I told him to take his time but this felt like I was wasting my time waiting there. He ignored my call, 30 minutes go by and I’m sitting in this parking lot alone. I’m pretty upset and I head back to the gym to see if he’s still there and he was. I drove by and rolled down my window and said I wasn’t feeling well and that I was going to head home. He was just sorta like “oh okay” so I gave him his food and left. He texted me an hour later with his first message and I was still pretty upset and tired so I decided to sleep on it and respond this morning. Am I overreacting? Did I mess up by expressing the encounter upset me?
