While we still do not have a definite answer as to how long he has been upset with the company, we do know now that CM Punk was already contemplating a departure from WWE as early as Royal Rumble 2014. He vented to Mick Foley at the time about not being happy within the company and having trouble dealing with injuries.
When Michelle McCool went in for wrist surgery last month, there were speculations that she was healing up for another run with WWE. However, that does not appear to be the case. No such return is currently being planned right now, as she is spending time with her baby daughter.
