Hello friend! Thank you for the kind words, I really appreciate it ❤️ here are some fics centered on jealousy. I did a few other lists for this trope over the years, you can find them here, here and here.
It only happened once — depending on how Harry counted.
Draco gets back at Harry for his late nights as an Auror by flirting with the new Arithmancy professor. Harry's not usually the jealous type, but he has his moments.
Speaking to Draco is like poking a beehive - and Harry is a glutton for punishment. In which Harry makes some serious blunders and then tries to fix it. Somehow.
Harry knew Draco was gay when he invited him to move in. He’s never had a problem with this. So why does he feel so weird about Draco bringing men home all of a sudden?
It’s weird when Hermione announces that she and Ron have broken up. It’s weirder when this is followed by the revelation that she’s already moved on—and the new object of her affections is Draco Malfoy.
Malfoy finds a coin. Harry finds a letter.
Months after their explosive break-up, Draco insists Harry return to their flat to remove his belongings.
“I don’t understand how this is of any concern to you, Malfoy,” Harry said, crossing his arms over his chest. Draco blinked at the use of his last name, something that Harry only used with him in jest these days. “I’m merely spending time with my Auror partner, who is from another country, and has no one here. I would do the same if it were you.” “It’s not me though, is it?” Draco all but shouted, unable to stop himself.
When Harry and Nott are paired up to go undercover as fake boyfriends, Draco is disappointed not to get the assignment. It's just professional jealousy that's making him feel so upset. Obviously. He's engaged to be married to Astoria, after all.
Draco and Harry have been flatmates and best friends for years, and Draco thinks life is just perfect that way. But when something comes along and threatens to take all that away, Draco has to decide what it is he really wants, and just how hard he's going to work to get it.
Draco never expected to see Harry doing that again. Especially with someone else, in a grainy photograph that's landed on his desk one Monday morning.
Draco is mortified when moments prior to departing for the most anticipated destination wedding of the year, he is cruelly dumped. But when he learns that Harry Potter has, at long last, split with his horrible boyfriend, Draco is certain his luck has changed.
