If you are asking someone to say something in Spanish you will use the phrase "en español porfavor" or "In Spanish please."
If someone is asking you for something or to do something then be honest and simply say, 'Thank you, but sorry, I'm not interested.' This goes for getting back with someone you have broken up with.
