Guy i’m seeing acting different?

I’ve been seeing a guy for a month. We’ve been on a few dates. Thursday night I slept over and everything was fine, except when I went home all he said was it was good seeing you. I texted him good morning which he replied but when I asked how he was all he said was tired. I responded but haven’t heard back since this morning. But he’s active on snapchat so I don't know if i’m just overthinking. Any opinions?
