What does it mean when my crush kisses me goodbye but we’re not dating?

Only the past couple of days I have been hanging out with my crush. He’s friends with some of my friends and we go to school together so that’s how I started hanging out with him. A couple of days ago we made out and now every day since then we have hung out as a group with our friends and he’ll kiss me goodbye.
he’s also very affectionate and isn’t afraid of pda, he’ll come up from behind and wrap his hands around my waist and kiss me and do all that coupley stuff but we’re not even dating. He knows I’m into him but I think he just wants to mess around, I’m not sure about his intentions. But my friends say if he’s kissing me goodbye then that’s more relationship kinda vibes. Would we be considered a thing? And why is he doing this if we’re not dating
