Horrified at the thought of their favourite couple being separated, they are now demanding that Danny Miller leaves too.
After five years playing Robert Sugden, 33-year-old actor Ryan is now set to bow out of the programme, as he is keen to "try other projects".
An ITV source told The Sun newspaper's Bizarre TV column: "Emmerdale fans have loved every minute of Robron's story, and what Ryan has brought to playing Robert. But he has decided to take a break from the show for the foreseeable future and try other projects.
"He will leave later this year, but fans can expect to see him on screen right up until the end of the year. He will be sorely missed."
Ryan's character has been at the centre of some of the soap's most dramatic storylines, including having gone through affairs, manslaughter, a prison sentence, and an inner battle with his sexuality.
Best news ever, it would be nice if they killed off both Aaron and Robert.
As the news sinks in, upset fans have jumped to all sorts of conclusions about Robert's departure - with some fearing he might cheat on Aaron or even be killed, leaving his husband inconsolable and alone.
One tweeted: "I'm hoping for a #Robron happy ever after. Maybe they could leave together and then have Aaron come back down the line if the actor who plays him doesn't want to leave."
Another said: "So... I have no doubt a lot of Aaron/Robert fans will want Aaron to leave too and live happily ever after off screen so they don't have to watch them break up or Robert die."
A third agreed, typing: "I don't know about anybody else but seeing Aaron with somebody other than Robert is going to be almost impossible for me to watch, and currently the only reason I'm watching #Emmerdale is for #robron."
"I can't watch them be parted again," sobbed a devastated fan. "I can't watch Aaron or Danny for that matter, with anyone else... The chemistry wouId never be the same... For me #robron are end game one way or another...ENDGAME #RyanHawley #emmerdale."
However, some viewers simply aren't a fan of the "horrendous couple" and claim they have "zero chemistry", with one simply writing on Digital Spy forum: "Can Aaron leave too please?"
Another said: "Splendid news. Can I be greedy and ask that he takes the ghastly Aaron with him? Only I'd rather not endure months on end of his crying and bellyaching, he's miserable and loathsome enough as it is."
A third gleeful viewer added: "Best news ever, it would be nice if they killed off both Aaron and Robert, so Robron dies forever."
"I wish they would write Aaron out with him," agreed another. "As Aaron feels so finished as a character and Danny Miller's heart doesn't seem to be in the work."
Ryan has played Robert since 2014, becoming the fourth actor to portray the character following Richard Smith, Christopher Smith and Karl Davies.
