I am a major critic of Rooney but its not fair to put him in a " damned if he do and damned if he don't " situation. He is not a bad person so he will always give the politically correct answer to such a question.
If I were him, however, I would take a pay cut and return to Everton, if they still want him, stating that as much as he loves Man Utd, the fans, the players etc, that he has always wanted to end his career playing for the club he grew up supporting.
Fans would understand and he would escape the embarrassment of not been sought after by other clubs, home or abroad.
