Mourinho was speaking after Real's UEFA Champions League semi-final elimination at the hands of Borussia Dortmund.
The former Chelsea manager said: "I know in England I am loved. I am loved by the fans, I am loved by the media, they treat me in a fair way, criticising me and giving me credit when I deserve it.
"I know I am loved by some clubs, especially one.
"In Spain the situation is a bit different because some people hate me.
"I didn't make a decision because I have a contract, but more than the contract, the respect I have for the club and the president.
"I want to finish the season, I want to try to win the (Copa del Rey) final, I want to try to finish second (in La Liga) and at the end of the season I will sit with Florentino Perez, my president, my friend, and decide the best for me.
"It is difficult to make a decision because I like the club, I like the president, we made a fantastic team that is ready to make big things, so it is hard.
"I need to honest and fair. At the end of the season I will speak."
