Guy's Behavior

He kept giving me sips of his drink what does that mean?

Hey guys so odd question I know but this past weekend I was at a wedding (I was actually in the wedding party) and a guy also in the wedding party kinda caught my eye. So I was dancing with a bunch of people and he squeezes in next to me doesn’t dance just kind makes eye contact and I smile. Later on he joins the group again and then he offers me a sip of his drink which I accept he watches me while I drink it. Well quite a few more times during the night either I came up to the group or he came up to the group and the same thing happened offered me a drink and I accepted and then we would chat for a few minutes. Well except the time I walked up to him while he was talking to my dad lol (still have no clue what they were talking about but I did manage to slip in the I’m single line 😂) well the next day I get a friend request from him on Facebook which I accepted and there has been nothing since. Am I reading too much into this? My sister asked me what was up with it and I honestly don’t know. I mean I’m used to taking 1 sip from someone else’s drink to try it but 10ish?
