guys, chill. when yuuri says he wants to “end this” he uses 終わる (owaru) which just means “to end” and is not something usually said when breaking up with someone (that would be 別れる wakareru). yuuri isn’t breaking up with victor, the language is purposefully ambiguous like that to fuck with people.
he’s probably talking about not wanting to do competitions any longer (did you see how exhausted he was????)
