Also in Omega Ruby and Alpha Sapphire, this conversation between an Ace Trainer and a Delinquint you find in Mauville, both female. If nothing else, it sounds like a breakup:
AT: "Eh? Seriously, ma'am? Ya gonna treat me to dinner?"
D: I told youse i would, eh? Ya managed to become an Ace Trainer, doll. We gotta celebrate somethin' like dat. Pile up as many o' dem Village Sub Combos or Magnemite Croquettes as ya want.
AT: Thank's ma'am! I'mma take you up on that!
D: Yeah, kid. You do dat. But dis'll be our farewell meal, y'unnerstand? Youse can't keep hangin' out wit' a hood like me- not even one with a fab do like mine. Not wit you bein' an Ace Trainer an' all.
