Does he have a crush on me or is he just nice?

So I have this guy friend in a mutual friend group and recently he has somewhat touchy sorta looks at me while laughing and the other day me and couple other friends we’re gonna grab drinks and I turned down the offer and he convinced me and was elated that I was coming. And now our mutual friend mentions his name a lot am I just being delusional or there is smthg going on but we never text we only communicate at work.
