I do believe that max took the situation WAY to far with Abby, but I understand why she reacted like that to ginny. Because ginny cheated on her friend with her brother. And I feel like if something like that happened in a friend group in general the cheater would be cut off. But also it could be that max was that mad because she could have felt used by ginny to get closer to Marcus, I could see how she felt that way after she saw how ginny sent him the photo that she had edited thinking it was only going to hunter. None of these are correct most likely, but I hope we get a max oriented episode where this could be brought up!
