Why did he kiss me on the cheek? What does it mean? What should I do?

I used to have a crush on this boy last year but he moved & we basicly stopped speaking. He's back in my city now & on Saturday a mutural friend of ours had a party & he was there... He knows I used to like him even thought we never spoke aboutalastair year.

When we first saw each other he hugged me, we talked for a while & did all the stuff u do when I first see some1 you havnt seen in a long while but then later in the night he grabbed me gave me a hug & kissed me on the cheek then walked off... I was very confused but slightly tipsy so didn't really question it at the time. It wasn't a quick peck tho he did it really slow as if he was wandering whether to do it or not.

Anyway I just wanted to know what you lot thought. he knows for a fact I used to like him so if he liked me now why wouldn't he just say so & what was with the whole cheek thing... Nobody saw it I dnt think but when we was around the other we both know he wasn't as friendly...he didn't ignore me it just the vibe felt diffrent

thank you
