Does this guy at work like me?

I’m 19 and he’s 22. We work at a fast food restaurant and I like him but I can’t tell if he likes me back or not, but after some research and looking up stuff that he does it kinda seems like he does but keeps it subtle. So I’m gonna turn to you lovelies for some help! For starters, some things that he does is talk to other people normally and fine but when he talks to me he can barely even keep up a conversation. (We talk every now and then during our shifts.) But when we do talk it kinda awkward and it ends quickly lol. I also noticed that he also keeps a close eye on me sometimes when I’m messing around with other guys. Aka joking and talking and laughing with them. The other day when we were working a late shift I was messing around with this one coworker I’m super cool with and then this guy tried multiple times to stand with us/ talk to us but it would get awkward lol. I also saw that when he sees me with the other guys at work he goes and talks to the other girls as well. He would also be around me constantly like he was trying to make his presence known is what it seemed like. I mean he literally walked in the area I was working at about 5 times to go in his phone for 5 seconds then leave or just walk down that little hallway area look around then leave. He also walked past me and kinda touched my arm to get past which is something he’s never done before. He’s just hot and cold a lot and it confuses me! It seems like we’re becoming closer as friends as well but I actually think this guy is attractive and I’m just confused! Someone help!
