its because, bella didnt パンチ paul, she slapped him and really あなた cant injure yourself によって slapping anything, but my punching あなた can, so quit the 質問 cuz ur wasting everyones time trying to explain why this is,
Well in the book she don actually ever do anythin 2 paul, in the film she kinda just slaps him, wheras jacob she physically punches him in the face full force-causin her 2 like break her hand.
Well it’s because Paul isn’t as strong as Jacob which is shown in their battle Jacob has もっと見る strength that being 発言しました he is the strongest in the pack which is why it hurt when Bella hit him
