Am I wrong? immature?

I started talking to this guy a few weeks ago. We've just made out that's it. Well anyway I saw him at the club last night talking to another girl. I smiled and waved at him. I continued dancing and having fun for the rest of the night. I saw him watching me once.. waiting for a girl to use the bathroom the second time.. then when I was talking to another guy he tried to get my attention but I ignored him then he left. He texted and asked where I was at the end of the night. He tried texting me the next day asking did I have fun and said he only saw me for 10 secs. I replied ok and we haven't talked all day. I deleted him from Instagram. Feel like he is playing a game. Sorry for the run ons and typos
