I agree with what you wrote, it's weird that Erynn spent the last 5 years hoping to see this guy, but one "wrong" move(that isn't even wrong, he's just helping his friends) brutally changes how she feels.
The reason why it could be written out isn't because it makes the story better in any way, it's because it makes the devs life easier since Nyx doesn't seem to have good plans on how to handle Erynn vs Layla...
So, it doesn't enhance the story, it makes it easier for her to write the next chapters.
It's bad from a players perspective, Nyx already knows who Erynn is, the MC has a contentious relationship with her... but at that spot the people who have to make this decision(us), don't.
Even if i prefer Erynn(despite not knowing her), leaving Layla and a pass out drunk Elena alone with an untrustworthy idiot(and Nyx makes sure to tell us, before and after this decision how much of an untrustworthy idiot he is) sounds like a bad decision.
A decision you might wanna make not because you are Layla over Erynn, but because the girls need you right now.
Of course, somehow this is the only Zach doesn't do anything stupid(other than fondling the drunk girl ass) and things turn out alright... but that's hindsight speaking.
Nyx apparently thinks that things staying quiet for so long is wrong in this specific case because of... Alexis.
This was the reason i think, Alexis is close to both Layla and Erynn... so she would say something... and interfere somehow.
Personally, i believe that's overthinking, it's unclear what Alexis knows about Erynn-MC, Alexis has never been present at any moments between MC-Erynn.
Erynn seems like the type of person to keep things like that pretty close to her chest, Erynn denies anything to Emily and Melissa, even when both of them 100% know it's a bold faced lie.
Iris also doesn't seem to know anything... she stops for Alexis, but keeps going if you are dating Erynn, which tells me she doesn't know.
So why would Alexis undoubtedly, 100%, know everything? I have no idea... but Nyx thinks she should interfere.
Not to mention this is quite possibly a touchy subject between Erynn and Alexis, if you dated Alexis in the early game... with the fight they had a while ago still fresh on their mind, Erynn would have way more reasons not to share anything about this relationship.
And if Nyx is convinced that Alexis would interfere, then by all means, add a scene where Alexis puts the MC against the wall and tells him she suspects he's "double dealing", but you don't have to kill everything as a "fix".
Yes, the best, most emotional, moments of Intertwined are often these scenes, i hope we get one for Layla-Erynn

Erynn doesn't know what to do when first meeting the guy after 5 years, she wants to be friends again, a relationship might interfere with that... it takes a looooong time for her to come around and start giving in to her feelings.
Still feels unreasonable that this small rejection, would completely change how she feels about him.
I can even conceive a universe where to combine Erynn and Layla you must chose Layla in that scene, Layla has more right to feel disappointed, maybe this guy isn't what she thinks she is... leaving her for another girl when she's in a dangerous situation.
Maybe selecting Erynn means Layla doesn't call him the next day about the beach derailing her path...
But Erynn shouldn't be this much affected, i mean she comes to the house to hang out with him the next day, regardless if you stayed or not... It sounds like she understood your choice, but somehow it's over?
It doesn't make sense.
I already made my case that Alexis not knowing much isn't unreasonable, specially if they fought over the guy.
