The strange dynamic in your relationship with Draco always confused you. It was hard not to be offended by his behavior.
Cold in front of other people, but with you alone he is the most affectionate.
Constant jokes directed at you, offensive teasing, rudeness and coldness... This is how he behaved when he was with you in front of others. And then, alone with you, he endlessly apologized and swore his love.
“Come on, don’t be offended. I love you..” Draco whispered, hugging your waist. He felt how you tensed under his touches, but did not pay attention because he believed that one apology would be enough. He constantly apologized and you forgave him. So it should work.
"My love, don't be like that. Stop sulking." Draco purred, which made you even angrier. You were really getting annoyed by Draco's behavior already. It was cruel. Why should you tolerate his behavior if he doesn't change? He can apologize every time, admit his guilt and mistakes, but this never leads to anything.
