To burn with desire and keep quiet about it is the greatest punishment we can bring on ourselves. ~Federico Garcia Lorca
I've done this a few times in my life - once with a person that I was completely besotted it, and twice when I wanted out of relationships that were completely and utterly stultifying to my soul. After the mind numbing, soul killing relationship that lasted 13 years too long, I decided that never again will I keep quiet about deep desires.
If I burn with desire for something, I will say so. I may not get what I want, but it won't be because I wasn't honest about my desires. I would rather feel the pain of rejection and failure than the pain of killing my own soul.
