The RAW after SummerSlam 2013 incident
Following his loss to Daniel Bryan at SummerSlam 2013, Cena revealed on RAW that he would be taking a leave of absence due to an injured elbow. Instead of receiving sympathy, the crowd erupted in cheers, effectively mocking Cena's misfortune.
In light of these incidents, Cena's decision to "break up" with his fans seems justified. The constant abuse and disrespect had taken its toll, and Cena finally snapped.
