🆘🆘🆘Husband acting sketchy??

So, my husband was acting sketchy yesterday. He's never given me a reason not to trust him before, but he acted weird yesterday. I've been cheated on before in previous relationships so maybe I'm overreacting:

He's a restaurant manager and he works about 45 minutes away, and has to commute everyday. We work opposite schedules, and I normally go to sleep, and wake up when he gets home. This is our normal routine.

But yesterday, he texted me at 10:48 PM, saying that he was almost done working for the day. This is normal. I go to sleep, assuming that I would see him in 45 minutes or so.

I get a phone call at 12:45 AM waking me up. He's saying that he's at Walmart picking things up, and he asked if I needed anything. I told him I didn't need anything. I went back to sleep. And I woke up when he came home at 1:25 AM. This is NOT normal.

I asked him about the timeline and he stated that after he texted me at 10:48, there were more things that he said he needed to do at work.

Am I overthinking this?
