No, you don't have to be on the not help her path.a It's either a bug, or you in advertently started a relationship. There are a few critical moments that can trigger the romance path for Erynn, even if you ignore some less significant moments.Also, I've been trying to do a path where I'm faithful to Nikki, but I keep also trying to be nice to Erynn because the poor abused girl deserves a friend. I don't go with any potentially romantic choices (correcting people when they say she's the girlfriend, not kissing her, not flirting with her), but when Nikki arrives, he still says that he's seeing someone. Do I have to be on the "don't help Erynn" path to not be a cheater?
If you open the Walkthrough in Original Post, search for the term "just friends with erynn" and there are a handful of cases where you'll trigger the non-romantic variable/path. There's only a couple of cases where "Erynn romance over" string matches but you have to already be in a relationship for these to trigger.
