He calls always calls me nice?

This guy I really like calls me the nicest person he's ever met all of the time. I haven't done anything THAT nice tht deserves him saying tht... I'm not complaining, I love it, but it confuses me. He'll tell me I'm the nicest person he's ever met then tell a bunch of people around us tht im the nicest person ever. He has done this sooooo many times. I'm always so flattered I just smile and don't know how to react... but why would a guy constantly tell u and everyone else how nice you are? Is he just being super kind and friendly (he IS actually super friendly and nice to everyone)? Is he sort of maybe bragging about me in a way? Or is he trying to tell me something? Like tht he likes me? Or that he doesnt? Any advice would help thanks.
