Just throwing the term out there on its own doesn't mean anything. Every story where the good guys beat the bad guys is cliché in that sense, it says absolutely nothing about the quality of the work.
Jackie looks like she's being served a big old shit sandwich right now, but the story is far from over. Marco might leave her for Star but I very seriously doubt he's just going to have a love epiphany out of nowhere and toss her aside.
More than anything it seems likely that Jackie's going to be the one to break up with him, because he's not putting any work into their relationship and consistently favors spending time with Star over her.
The current situation is really shitty for Jackie, but nothing that happened for things to get to this point was forced or contrived. And the story will be better for it; Star and Marco will have their own problems to sort out, and Jackie can be more than just a love interest.
