Guys, I think I fucked up. How do I get him to talk to me again?

So my friend and I hung out Friday into Saturday. We had fun the first day. The second day it was awkward. We barely spoke to each other. I tried to fill the silence by asking him questions - but he was really short with me. He didn't really ask or say much to me. We were both exhausted though.

He didn't make any moves on me, so I don't know if he was expecting sex or what. I would have if he'd made a move. But he was very respectful the first day, he was pleasant the second.
