I figure the crumpled note can go one of two ways.
1) He's angry and frustrated that Celene isn't coming (likely this was how it was intended to be interpreted, given the axed Celene subplot, and the "crumpled" aspect is simple another one of those things that didn't get fixed in rewrites.
2) He's disgusted at Celene's hinting about a marriage alliance. Whether that's due to his devotion to Anora, or the fact that even Cailan isn't idiot enough to fail to see that attempting to marry the empress of Orlais would go over like a pregnant pole vaulter is completely open to interpretation.
