Why hasn’t he accepted my friend request?

I was at my cousin’s wedding on October 29, 2016. I met this guy who is a year older than me. He and I danced the whole time at the wedding. We had a lot of fun screaming and jumping around. One of my cousins noticed and told me during the reception that this guy was feeling me and seemed to like me since he was always dancing with me. At the end of the night when we had to go our separate ways he told me to find him on facebook which I did. I sent him a friend request. He has not accepted it yet. I saw on his profile that he doesn’t post often so I assumed it’d be a few days until he sees it. BUT he did post a status update hours ago. So why did he not accept my friend request? He definitely acted like he liked me during the wedding. What should I do? Continue to wait for him to accept the request or should I just leave it alone cuz he was probably drunk when he was dancing with me? Help me please.
