Summary of core abuse points
1. He loves her, but he must push her away - his undercover status prevents him from getting close
2. She loves him, but thinks he doesn't love her – all confessions are missed
3. When he died, she was getting married - at the same time, separation and death happened at the same time.
4. It took her four years to know he loved her—and four years since he was dead
5. After she found out, she chose to die for love—not because of cowardice, but because she kept her appointment.
