It wouldn't, and we don't know if she is getting fucked at work, but we see an asshole grabbing her ass like she was a hooker or he was "entitled" to do that, so most players speculate. It's something serious, she wouldn't be crying if it wasn't.
Also, Erynn is in this situation for quite some time judging by how she says that she can't do it anymore. The MC left to stay with Andres, and she didn't know when/if he'd come back, he wasn't present in her life so the players can feel betrayed by her fucking Ethan or fucking for money. If she's just eye candy to entertain rich assholes, a stripper or an escort is up to the dev to clear it up, our job is to play and enjoy the game and its story.
We starting another misinterpreted "confession" debate here, so let's stop at what you said... harassment, and all that stuff is dealt with by telling the bouncers to tear the dudes a new one, if they sick in the head and stalk her or force her to do something she don't wanna do, there's police to deal with that. "Mentally broken" is a little far-fetched, but it could justify her possessiveness and her "craziness" that you ppl kept talking about on that Erynn crazy train.
It seems she's being blackmailed by Ethan, how else could she explain why he's still present in her life and also her "work" related whatever he is. The cunt bullied the MC in her presence, lied about Alexis (why would she be angry at Alexis for fucking him ??) and he's probably responsible for the shit she in, her excuse is... plot armor, next best thing after the MC ??
