Dating help


I’ve been dating someone for about a month. Everything was going good in the beginning we went on a few dates I thought he was really interested in me. The. I went out of town for my birthday I didn’t hear from him at all I came back I called he didn’t answer. I’m not sure if he was mad at me or what so I called a few days later over the weekend and he said he wanted me to come to his house and we could talk when he got off work. I called when he got off he said he was late getting off and he would call me back but he never did. I happens to look at his friends story on Snapchat and it looked like they were drinking and having a party so I called and he still didn’t answer I texted him and he never responded. What did I do wrong or is he just not interested in me or dating someone else I just feels like he playing games
