My childhood guy best friend touches me when we’re together?

Lately, when im with my guy friend he is always coming up to me and stands so close and will grab my butt but never say anything, or he’ll come up behind me and grab both of my hips and pull me close to his body. It seems that personal space is not a thing when he’s around me. He is also will grab my face while he is talking to me, or pull me in closer by grabbing my waist. He has never said that he’s likes me or wants to be with me, and im scared to bring it up I dont want it to get awkward and ruin our friendship.
