Is he interested and should I take him up on his offer?

I saw my crush recently, as everyone came home for graduation, and I think he’s starting to warm up to me. I talked / joked with him during the ceremony. I made him laugh once but expected that to be the last time we'd talk. Surprisingly he came over to where I was with my friends and we all talked as a group. I was caught off guard when he told me “we should meet up” and I said yeah that’s be great and we actually hugged before he left. All of my friends said he was directly talking to me and pointed out how he only asked me to “meet up” and only gave ME a hug.

It makes me wonder why he would only hug me and only ask me to “meet up” when he’s friends with my best friends as well? And why he would do both those things in front of my friends, if not to show me he’s interested in just me specifically? Now I’m wondering if he might be interested and if I should message him again and take him up on his offer, or even just to chat some more?
