We had our 2nd date and our talking dramatically decreased after this happened?

Maybe I'm over thinking... maybe I'm not.

I met a guy on 4th of July through a family friend's house. We hit it off, he got my number and we've been talking. We went on two dates. Thursday and Friday. Thursday was a great date!! Friday was great but... we went to an arcade/bar thing. We were both tipsy so we ended up at my apartment since I didn't want him to drive home like that. My friend gave us a ride to my apartment.

We made out and had s*x. It was great. We crashed out til later that morning. We woke up, I made him breakfast, we freshened up, and we went to go get his car.

We didn't go to sleep til 5am. So Sunday I slept all day. He worked a 14 hour shift. So obviously he didn't talk to me yesterday which I'm perfectly fine with that since he needs to rest. Today he took a long nap after work and when he woke up he didn't seem interested in talking to me with the way he was texting me (silly I know but us overthinkers can tell when someone's vibe is off). He did tell me he was tired...

Am I overthinking this?
