I can't speak from experience, but I'd guess he's probably fine. Bettas are interesting little guys and gals and have quite large personalities. If he's eating, looks healthy, and is otherwise acting healthy, my guess is ... he's fine.
My betta Caesar follows me around the downstairs, always staying on the side of the tank that is closest to me. He will also go back and forth between people conversing, staring at one and then the other as they talk. He's recently taken to being quite friendly with me when I feed him, and rubs against my fingers as though he were a cat.
So safe bet? He's probably fine :)
