@Catwon then why is peter trying to take revenge? One man has his own choice to date someone, if jennie is rejected she should always respect the other party's opinion.

@Catwon But wasn't it? She believed that Phillip liked her, and was obsessing with him. Badly. She had expectations that they would be together or whatever, which is why she wants going to such lengths to be with him. I imagine that she confessed to him, he rejected her. Perhaps he started dating someone at the time and she wasn't able to stomach the fact that her 'prince' was with someone else. Either way, it broke her, because it broke her expectations of having a fairytale romance. It was the straw that broke the camels back, so to speak. That's the most probable as why she commited suicide. Why else do you think she did if not so, especially when the hints are all over the story and flashbacks?
