Man oh man oh man. Confession: I stopped watching after she had that fight with Eric. She went from so-so for me to totally unlikeable with her indigence and refusal to consider his point of view. I had only watched JP's season for a few episodes, so I wasn't as enamored with her as those who had watched, and all I saw was a self-centered, dig-in-her-heels, not-particularly-empathetic figure.
Anyhoo, all of this is say that this current Nick debacle is of no surprise to me. There were several times throughout the season where Andi really showed her true colors, and I just thought: Ugh, why am I watching some stone-cold bitch dick around a bunch of in-the-bubble guys? (I know, I know, that's the show! But I generally have to at least tolerate the lead to justify spending two hours of my week watching it.) Listen, sure, leading these guys on is part of the deal. Showing absolutely no empathy and responsibility is not. (As plenty of others have said already.)
Good luck, Josh! I can only imagine how the fights will play out in your house. (Actually, I will imagine it: Andi will always be right.)
ETA: Quinn13: I felt the same way watching the Emily-Arie break-up. That's when they started to lose me as a religious viewer. Add in the gross treatment of Brooks (and humiliating Des, who admittedly, I was never a fan of, but yeesh), and I was finally (nearly) cured of this crap.
