All that actually happens to Jade is she is getting divorced from the man she hates, and she doesn't receive any of his money. Why are we acting as this is some sort of terrible fate, never mind one that she doesn't deserve when it's largely her own doing?His flaws + her flaws = failed marriage.
Stefphen was a terrible father who didn't care about his children and he never had the courage to say it in a year, he always gave in to Jade. Jade took advantage of Stefan's weaknesses for years. It's a toxic relationship. But in this situation, she may not be the victim as you say - but it's undeserved and too much.
No one made her fuck her own students. She's the active party in that, and one stupid enough to pick a student at her own workplace as her target. At the end of the day she gets away from this largely scot-free and still able to make 6 figures a year with her excuse of a job.
