I want to know how you interpret this situation, since I do overthink?

I do overthink a lot, but my instinct can be accurate sometimes, so please let me know what you think. Thank you.

I've noticed strange behaviors of the guy that I'm dating - supposedly - exclusively, based on what he said.

We were going to cook something at my place. He asked me if I wanted to meet on a Saturday evening. I said I was thinking lunch and asked if that wouldn't work for him. He said whatever worked for me with "😘" Emoji. I asked if we could do lunch then and he agreed.

We had lunch, also had sex once before and once after lunch. (No, I didn't just meet him. I'd been going on dates with him). After the second time he went to shower and put all his clothes on. I asked if he wasn't going to have dessert. He said yes, just wanted to get ready, since he had to leave by certain time so he could be "home" by certain time to work on something he needed to submit Monday (he did tell me what that something was.)

He said that's why at first he thought he could work on that earlier that day and meet me in the evening, but we met for lunch.

When we were having dessert, I saw him checking map to a place. I casually asked what he was checking (wasn't trying to keep tabs on him, we both are foodies). He said it's a place that was recommended to him as a good place, he wanted to see if he could stop by on his way home to pick up food. I notice he was checking the distance and driving time. I said I knew that town, not far.

After he left, I was checking out that place he said was good, noticed that the place had 3 point something stars of reviews. I realized that all his behaviors were indicating that he was going on a date with another woman: he showered, had a time in mind when he had to reach a place ("home"), was checking the drive to a place. After that his texts had been just words and no Emoji. His baseline was a lot of kissing and heart eyes Emojis.

I think he swapped his dates, went on a date and has been seeing somebody else. Am I overthinking?

I could ask him if he's seeing somebody else, which I did before and that was when I think he made it seemed like no, (without a direct "no" though), but I wouldn't ask over text, and he can still lie even if he really was seeing somebody else.

I asked him on a previous date, where we stood, he said "we're dating." I asked if he was seeing other people, he said that he doesn't do "non monogamous like some people." He said I could check his phone and he didn't even have the dating app (we met on CMB). I could still see his profile so I know his account wasn't deleted. I don't know if he had been active (as I'm not a paying Premium user) & try not to find out because I don't want to be a detective woman.
