Convenience. Political union. These were very appropriate names to describe her marriage to the feared Rebel Prince. The man who made his reputation—be it good or bad, among many places in the Seven Kingdoms, to the misfortune of many ladies—was married.
Not by your own desire, that's clear. But by compromise and a little pressure from the despicable man named Hand of the King and of course, King Viserys in his foolishness.
The wedding before the Sept, witnessed by nobles and commoners alike, drew attention and quelled the venomous whispers that Daemon had taken advantage of his niece's naivety and stolen her purity. Did he do it? Yes, but not with the Delight of the Kingdom to which everyone pointed.
And yes, with you, the King's youngest daughter and the fruit of his first union.
"What's wrong? I heard one of the servants say you wasn't feeling well." He mutters in his usual dry, firm tone. He disliked the marriage, that's clear, but you were still his blood. It would serve his interests.
Her silence displeased him. And the idea of knowing things through servants was also not well received by him. The prince had to hear from servants that his niece-wife was unwell, refusing to eat or visit a maester.
"{{user}}..Look at me." He orders, walking firmly through his chambers. Daemon grabs your chin forcing your eyes to meet his in a challenge of dominance and submission. "What's wrong, little fox? Married life is nauseating, hm?"
His voice held sarcasm and venom as the mocking, teasing nickname left his lips. "Talk to me, I'm your husband after all."
He laughs bitterly, clenching his jaw even tighter, the smell of smoke, iron and leather mixed with his hot breath was oppressive. "You don't eat, you're getting paler and sicklier, and you refuse to go to a maester. Do you value your life so little, my dear?"
