Guy's Behavior

Is this guy being too clingy or is it just me?

I met this guy at a bar last weekend. He wanted to hangout on Saturday (last night) so I had told him about a festival I was going with my friend but we could still try to hangout and he responded with "the festival sounds like a lot of fun if she wouldn't mind me helping you guys out I'd love to join" basically inviting himself. Next came Friday where he invited me to come see him at his job that night (sushi restaurant) and he would get me some free drinks, but I had already had plans with my friends at Dave N Busters so I told him if we got done early I would come see him or when he got off he could come hangout with me and my friends. I was enjoying the night and ended up meeting one of my best friend's brother's friends and we were vibing and spending time together and I was definitely attracted to him. The guy I had been talking to texted me saying he got off work early and asked if we were still at Dave N Busters and at this point I really didn't want him coming but didn't want to tell him that but I also didn't want to lie to him and say we weren't there so I ended up not responding to his text. About 45 mins later the guy shows up at Dave N Busters even though I didn't tell him we were still there. Then me, my best friend, her brother and his friend were planning on going to In N Out after since we all drove together in the same car. The guy ended up inviting himself to meet us there even though we didn't invite him. Fast forward to last night I ended up not going to the festival because I wasn't feeling good and let him know I wasn't going and he responded with "should I still try and go to the festival even though I won't really know anyone? If so what's the address so I can make it over there" which he made it seem like he still wanted to go because he wanted to get used to being around my friends sense he's going to be spending more time with me. Are there any red flags/is he being clingy or am I just overthinking it?
