Jenny is already pissed after how Harry talked to her, and how he wanted to take control over her life, and how he ordered her to not talk with her friends anymore.
She had no idea how Harry even thought that she would listen to his orders. Telling her not to talk to Amon was one thing because she can admit that she crossed the line with Amon even though she is in a relationship, but ordering her, shouting at her, telling her not to talk to her friends, anyone pushed the line.
Ember and Witney might be sluts, but they are her best friends, friends who even helped her financially when she needed it. Of course, Harry doesn't know this because Jenny never told him about it.
She couldn't believe the man Harry was turning into, and the more she thought about it, the more she started to wonder why she was even in a relationship with this man.
